The correct way to adjust this low speed needle, is to turn it all the way in until it is lightly seated. You then turn it back out 1 1/2 turns. That becomes a reference point for further adjustment. I like to be able to get a equal rotation each way so set the knob at about what would be 4 on the top. This should give you a basic setting. Once you get it where you want, you can pull it off , then reposition the knob where you want it. With the motor warmed up and the twist throttle in a SLOW position approximating your intended slow/trolling speed, turn this low speed needle jet in about 1/8 of a turn, let the engine run for about 15 seconds to respond to your new setting. Do it again then wait for the results. A cough is indicative of a rich mixture. Too lean it will just die. When you make this change and the engines either sputters or wants to die, back it off the the last position then this should be close to the ideal setting. If you go to rich it will cough AND then die. You can now pull the idle knob forward and off the splined shaft, reposition it so that the knob pointer is down so you will have movement either way from this position for fine tuning if needed. This low speed setting does not effect the high speed running of the motor. However it you set it too lean, you may later have a issue with it not wanting to start when it is warm.
1st, Rest in Peace Pepper. Pepper was the star of the show! Clearly, such a great companion. 👍 Onto some Yachting... Since Ben can do this with his eyes closed...lol I'll add to the concept. The factory setting on nearly all the metal 9.9/15 carbs is ~1 turn out from lightly seated. Neverless, it'll start fine at 1.5 turns out. The most important technique is to rotate the needle in until it begins to slow down(too lean) - make a mental note (like on a clock) . Then, back out the mixture screw(counter-clockwise) to richen until it just begins to slow down (too rich). THEN SET IT MIDWAY BETWEEN BOTH NOTED POINTS on the clock. After rotating the needle to the midpoint, pull out the knob and re-install with the tang facing staright down (6 o'clock). FYI-Normally, it's ~ 180 degree total difference between too rich and too lean. If you'd like to slightly richen it as many shops do, rotate counterclockwise (back out) ~5minutes if you view it as a clock. This process can start in neutral, but must be completed at a low speed in gear. I actually prefer reverse, since it's the toughest to idle at (exhaust gases), but forward is fine. A filled barrel is fine. In gear at idle stomp on the throttle momentarily, if it conks out, then it's slightly lean. 2nd test at idle, stomp on the throttle momentarily then immediately back to idle(closed throttle). If it conks after the abrupt drop to closed idle it's slightly rich (though it may be satisfactory in normal use). As Ben said, slightly rich is better than slightly lean. Next step...let it sit for 10 minutes off and it should restart without throttle. If it doesn't re-start, give it some throttle and retry. As these motors get older, there may be a compromise and raising the idle speed might be part of keeping your sanity. FYI- For the points motors '74-76 NGK B6HS, for the '77-1992's we've gone to NGK B7HS. Champion plugs seem to have a lower quality nowadays. We often will "Index" the plugs which allows for a bit better running at idle, especially if slightly rich, but that's a whole different topic. We stock index washers, so it's just a few more minutes of time. Hope that helps.
Thanks for the response. You and Pepper keep putting out those videos! It would also be cool if you videoed the maintenance you did to the motor prior to testing it out. I know it is probably a pain, but it would be some real good information for people. I know I would love to come to your shop and watch/learn when you do some work on these older motors. I might try my hand at those older motors myself one day.
Matthew Olday The videos that i have done that with i have had some very bad comments, and i don't think i will do anymore of them. Sorry....I will keep making videos of motors.
Good to see you back on here again..I missed seeing your videos..Its been cold but no snow..only once this winter..and boy we need the water..if we don't get some soon..will have to fish out of a can..Its been too cold to work out in the garage and I do have a 15 force to fishing up..Son still hasn't run the engine yet..Al work and no play at his end of the world..can you give me the name and phone number of that guy in LA..if he come by to go to Tomahok this year..I got a old green Johnson and a
Have a 1984 yamaha 8LN motor. Was running great at WOT one day and then in the middle of a lake just stalled out and would hardly idle. I cleaned the carb, although it wasn't very dirty to begin with, and also I've checked the plugs and they are good as well. Any ideas as to what could be wrong?
Coukd you make a video on how the pull start bendix style gear works and how to replace it. Mine has little spring tension up and down. And the nut likes to loosen on me....
I have a 74 15hp evinrude. It cranks up every once in a while for a few seconds. I messed with the lean/rich dial, the choke and the throttle but I can’t get it to keep running. New spark plugs. What do you suggest? Do you think I should take out the carburetor and clean it properly?
Hey Chrysler guy!!! Love your V’s very instructive... I have a 84 35hp Chrysler that crank on but after 30 sec it dies. I don’t know what’s going on. What do you think?
Where do you start with the mixture screw? When you build it and put your knob on is the screw all the way in or do you start with it out a couple turns
Every time I back the cam follower behind the cam plate hash line it dies out and doesn't idle do I have to screw in the idle control knob to constantly keep slowest position with the follower lined up with the cam hash ?
i have 1991 evinrude 15hp (E15REIA) idles perfect runs perfect but doesnt go any faster after half throttle rebuilt carbs twice, new spark wires,fuel pump, spark plugs, only thing left is coils but one time on the lake it cleared up and ran like a bat out of hell but only did it once. any idea of whats going on? 125psi compression in both cylinders.
I have one of these and it seems that it is very hard to get the throttle control to move once you get close to full speed.The piece that rotates under fly wheel that throttle cable moves seems hard to turn.Any ideas.I have nothing to compare it to.
hey...I just bought a 9.9 hp Johnson 1997 mod. who had been upgraded to 15 hp by taking out the filling...so i was just woundring if i could get more juice/power if i changed the carburetor to a 15 hp carburetor ?? thanks..
Im having an issue with my new to me 15 johnson not running well while trolling at low speed. it seems to flood out and doesnt want to start right away after it dies. the motor runs fantastic but yea, it will flood out and die after trolling for a short time. should I lean it out?? Im a bit confused
Also, if the idle knob is taken off can it be install in the wrong position and how do you know if it was, since I am at least the third owner and i could be on in a wrong clocked position?thanks
Hey my adjuster knob fell off and the out board has been stored for a long time so the idle screw is way out of tuning. Do you know about how many rotations it needs to be set form all the way screwed in?
Hi I have a question... Where you had your finger now to the other side when rolling the throttle is a little black plastic part that has a spring... Mine came off and don't know where it goes can u show the motor slow so maybe I can see on ur motor?
Is there a carb needle replacement needed to run at altitude of 5600' ? Just got an Evinrude 15 up and was told it was not set up to run at that high of an altitude
Thanks Dude. I'm thinking i will go about 10 mph @ 250 miles = 25gal. Do you think that sounds correct ? I will start looking at ebay for parts . And thanks again .
There's also a high speed screw on the left side of the carb. The shifter side of the engine. Its a fuel mixture screw with a T on the end so you can turn it with your fingers, thats only for high rpm tuning though and unless there's a carb issue you shouldn't have to move that one more than 1/8-1/4 turn in either direction...
Hey Ben, love your videos. Wondering if you could answer a question for me? I just bought a 1987 15hp Johnson and it's got it a sticker on it that says 100:1 fuel ratio on it. I asked the person I bought it from and he agreed that is the ratio he used. I read around on the internet and some people say use 50:1 instead. What do you think?
Matthew Olday From what i have learned about this is, OMC recalled the motors with the 100/1 sticker and replaced it with a 50/1 sticker. If it was my motor i would use 50/1 or even more oil. I have a 30hp and a few 6 and 8hp motors that say 100/1 and i use 40/1 in them.
On my chrysler 10hp 107ha the line u reference to line up roller with on the mag plate will only line up with the roller on the throttle control at full throttle. Motor wont' start and pull plugs and flooded. It has good spark both cylinders. Cleaned carb. Is this a timing problem? Any help appreciated.
Hi I have a 1968 6hp I think I have it to rich but have been told if it's leaned to much it can cause engine damage is this true? How do I lean it properly?
Could you take a look at my latest video of my 15hp? I zoomed in on the roller position to see if it is correct. My motor is apparently missing the idle speed adjustment screw. There is only a knob with nothing attached. Thanks! You're videos are great!
Hello. I have the exact same motor year and hp. One main issue I have is after I start it with the throttle set to idle. It hesitates and shuts off. Can this be corrected by adjusting the idle on the carb with either of the two screws?
Great video! I have a 1985 15hp Evinrude I've had since new (and it still looks new) and it sat for about 3 years. Cleaned the carb, new plugs, new grease in the low end, new tank and new fuel lines. Idles like it's brand new but once I'm running along and get to about 85-90% of throttle it starts to lunge up and down between 95-100% and down to 75-80%. Up and down....Up and down. I played with the fuel mixture for a while running up and down the river but it doesn't seem to change anything at higher speed. Any ideas would be greatly appreciated. Thanks!
Joshua Auckland It might be time to re clean the carb, sounds like the hi speed jet is dirty. it also might have a vacuum leak at one of the crank shaft seals, or might be a problem with the fuel pump. What do the spark plugs look like?
Hi I subscribe to you I find you extremely talented outboard engineer could you let me know where I can get two under flywheel coils for a Chrysler 20 Hp model No 2033 I’m in the uk I know postage is ridiculous ,
Hey thanks for the video. I have the exact same motor, can you tell me what the knob on the side of the motor is for? Behind the tiller handle on the side is a knob just like the mixture screw on the front, it looks like it affects the throttle somehow? Do you know what it is?
need your help engines giving me troubles. it will start with the choke on and run for approx 2secs then dies a lot of fuel coming out of carburator when squeezing primer bulb.. when i close choke the engine won't start.
Hi C dude I'm working on one of these .. runs great trolls great but when going back to high speed it seems to bog out and catch up after a Lil bit .. almost sounds like it drops a cylinder then kicks back in ...if the roller is out would this cause this effect being the throttle position is slightly out of time .. I know Ill work it out but a Lil help goes a long way .. more familiar with newer stuff Yamaha and Hondas thanks in advance my man . Canadian Mc tech Pat
Try adjusting your fuel settings. If they are off too much gas will get in and the engine won't burn it all and some can get past the rings into the cylinder
Dear Sir, Really Enjoy your Videos, I have been restoring a1964 Sears 14 Ft. Boat and Trailer. I want to keep the Motor I buy to be "period correct" and have found a 1963 Evinrude 6 HP and a Ted Williams 15 HP though I don't know the year. Both engines have been in Storage @ 15 years and was assured they were Both in Good Running Condition. I have not bought one yet but wanted to know what to look for and do you know any Reliable Mechanics in the State of Georgia. Thanks again for Any advice you might can give. Rick Shumpert
sorry to be so offtopic but does any of you know of a way to log back into an Instagram account? I was dumb lost my password. I appreciate any tips you can give me
@Kade Dane Thanks for your reply. I got to the site on google and im in the hacking process now. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
Hey my 1968 Evinrude sportwin 9.5 idles well but not on slow .. when I go to shift I have to do it quick or it stops it's runs great other then that what would you suggest
first - thanks for taking time to make & post video. I have the same OB (9.9 hp) mine starts and runs fine but......if I back the throttle "all the way down" it will stall. do you think I can just adjust the idle screw?
I have a 1980 9.9 Johnson. When I prime the fuel line with the primer bulb, gas is coming out of the carb where the small breather screen is located, on the side of the carb. Is this bad? Engine won't stay running. maybe sucking to much air. Thanks!!!
Well there are only two ways that would happen #1 needle and seat in the carb is leaking or #2 is the float in the carb is bad. It's time for a carb rebuild. This is the kit you will need. www.marineengine.com/newparts/part_details.php?pnum=OMC0439072
Hi great video. I really need some help. I cannot tune my carb. It's 87 15hp late model with black plastic top. I have new throttle roller . All new carb kit. I get engine idle but on gas it Biggs down and dies.
Hi I have about a 2000 15 two stroke and it will not idle. I was curious about the line on the timing plate. I think I heard you say it should line up with carb wheel when at idle. There is a screw on the linkage back by the plugs is this for setting the line? also it seems you can adjust the ramp with that screw in the plastic a few inches from the line. Thanks for any information.
On that motor the 1st thing I would look at is the cylinder head bolts they have a tendency to loosen up over time and cause poor idling. The 2nd thing I would check is that there is a rubber hose inside the carburetor that feeds the idle Circuit and they will turn to mush. 3rd thing is the top plastic carburetor cover is well known to crack.
So I just got a 9.9 Evinrude that's been pickled it's really clean hasn't run for years but like I said they said it was pickled whatever the hell that supposed to mean LOL I guess it was put away properly but it doesn't have a throttle arm which is okay because I have a sailboat so I steer it with my tiller on my sailboat but it has an electric start and I've never started one without a throttle arm... No I have started a car under the running things using the carburetor and you know throttling it like that but not now bored with an electric start and I'm a bit tired it's been a long long treck and I don't know what the hell I'm doing can anybody help me it would be wonderful thank you
I've got almost the same motor (25 evinrude). I took it out yesterday and when I left the boat ramp and throttled up, it didn't really do anything. I tried chokin it and still nothin. Then I blocked off the intake into the carb with my fingers and it took off like a rocket. I had to block off about half of the intake. Any clue what would make it run so lean?
Thanks man. I did leave the tank unscrewed a little last week when it rained. But on the return trip yesterday the motor ran like it should. So hopefully I just had a little rain water in the tank. Thanks for your quick feedback man!
i currently have a 1976 johnson, it was runing perfectly until someone played with my lean screw and now it idols perfectly fine but when you give it any sort of throttle it just wants to die in gear, could this be I just have to play with the lean screw and put it back so it runs rich again?
I took off my lower unit on my 1979 Johnson 15hp and whole changing the water pump impeller the drive shaft came out of the lower head. Now I cannot seem to install the shaft back without the “ nut “ on the shaft going any further down. It won’t allow for the new plate to sit flush on the head. Any ideas what happened ???? I would rest appreciate if you can help. Thanks
Pull the shaft down(shit into reverse) and it should reach. Ooops...I misread. Did you turn the prop shaft slowly while you try to slip the shaft back in place so it lines up?
Hi I have an old west bend 6 hp motor that only fires for a short while when fuel is added to spark plugs. I’m guessing the carb needs a good cleaning. But I can’t find any how to videos or any information if I’ll need new parts to clean it. If you can get back to me that would be great 👍 or email address for contacting
I have an 91 evinrude 3hp and experiencing the same problem... When I put it into gear it runs rough, the more gas I give, it starts to choke then dies. It seems like the throttle is releasing too much gas or something?? Is the throttle feeding too much gas??
I'm currently cleaning up one of these motors, 1981 15hp more or less an identical motor, minus the throttle linkage. The motor i have has never idled according to the past owner and i couldn't make it idle either. I just rebuilt the carb but it wasn't all that dirty. It's winter here so I can't test it, but could you maybe let me know exactly what screw you were referring to? Mine is missing the idle knob on the left side of the motor but i'm told that doesn't have much effect
Well 1st off you will need that idle adjust knob, without it you will not be able to set the minimum engine speed. Now if i remember the 1981 does not have a throttle lash adjustment screw. When it warms back up again make a video of what it is doing and i will help all i can.
chrysleroutboarddude appreciate the response, i talked to a few guys and they said the idle knob wouldn't make a huge difference and that it should idle without it, i actually found the retaining pin and the plastic knob inside the motor, the knob was gone though..the screw it looks like you're pointing to, on my motor is an allan key head on a piece of plastic, it doesn't appear to have much effect on anything? as the motor is sitting in the dining room i could email or post a picture thanks again
chrysleroutboarddude imgur.com/sg4lKhg this is the screw only screw in that area, it's attached to the throttle, though the 1981 doesn't have a throttle cable it uses the gear teeth (terrible design) this screw doesn't really appear to do anything it's just screwed into plastic
ryanbreeze Well the idle is set with a combination of timing and throttle plate position and fuel mixture. What that screw does is set the position of the throttle plate in the carb and when you open the throttle on the carb with the engine at idle it will lean out the fuel mixture. so that is why you have a low speed idle mixture needle. The idle adjustment knob sets the timing, and if you can't set the timing there is no way to get the throttle cracking screw set correctly. For a starting point close the idle mixture needle all the way, then open it 4 turns, then set the throttle cracking screw so that the throttle plate just starts to open when the roller lines up with the line on the mag plate, then set the idle adjust so the timing will not go lower then the 1st line on the mag plate. Start the motor let it warm up then you will be able to fine tune it by adjusting the cracking screw and the fuel mixture needle. Then and only then you can set the lowest idle with the adjustment knob on the side of the motor.
chrysleroutboarddude i really appeciate the responses, were you able to look at the picture i posted above to see if that'sthe throttle cracking screw you're referring to? i took a pic of it, as it's out of my motor right now, just doesn't seem like it does any actual adjusting. (sorry very new to this, first outboard)
chrysleroutboarddude - I just bought the same motor in your video. I also have the same problem, being a broken idle stop knob. A new Idle adjustment plastic knob & retaining ring from Amazon, $36.00 is on its way. My question is, why do I need this, on my previous motors mostly Mercury, there was no such thing, you would turn the throttle to start and start the motor, then when stopping I would turn the throttle down and shift to neutral. Please reply.
You dont have to have it if it idles fine and you dont need to adjust it for trolling. Thats all its for....allows you raise/lower idle without adjusting anything on the carb. I know this is old post but just in case you never got an answer.
how far should you have to twist throttle in order to start?I asume this determines on the one adjustment screw you talked about.Also, if I have the throttle twisted all the way off should that little roller be hitting or just barely touching the piece it rides on?My roller is pretty far away from the piece it rides on, so I have to twist throttle pretty far in order to start to open throttle to start.
So I checked the jets, they're brand new with nothin cloggin em. Only thing I can think of is a vacuum leak in the carb somewhere. You got any other suggestions?
Just checked the plugs... Put brand new plugs in before I took it out last and the bottom plug is fouled. There's fuel from the pump though. I'm stumped
I have a 1979 Chrysler 7.5 that I have been trying to get running, and i have done everything the manual says to do, but the engine will only stay running for about 3 seconds before it dies again. It wants choke on to start but immediately wants it off to run. There have been a couple of time when it ran fine for several minutes and especially well at full throttle, but now I cant keep it running. Ive verified compression with a gauge (100psi on both cylinders), replaced the fuel lines, fuel pump, cleaned the carb and adjusted the float and mixture screw, adjusted the stator control link and throttle cam follower, gaped the plugs all per the manuals instructions. It seems like a fuel problem to me but I don't know what else to try! you seem to have great success with these motors, and was curious if you had ever run into this?
I just bought a 85 15hp evinrude. When it's cold and it first starts up the rpms go crazy (I'm no mechanic). Just when I think I'm going to become a human drone, it goes to "normal" idle and runs smoothly. But when in forward I can't go more than 8mph in a 14ft smokercraft. It seems like I should be able to open that up and get about twice the speed. I suspect the butterfly valve is not opening all the way. Anyone have ideas? Please go easy on me. Thank you!
@@hippomicheo484 one cylinder wasn't firing. thought I had it fixed. new coil resolved. but now the thermostat is bad and it's located way down below the rear cowling, so I can't get to it. gave up. sorry.
You need a book when you adjust the carburetor on that motor the throttle needs to be closed tight there is no other way to adjust it properly read a Johnson service manual and it will
Great video dude , I started out to ask you or anyone what the MPG of a 9.9 johnson ? An EDUCATED GUESS ? , for a no gas station for 250 statute miles trip i'm taking 11-22-14 ,dose anyone know ? BUT NOW i see you are the chrysler outboard dude you might have parts i need for a 3.6 chrysler , I need a pull cord ass, it comes strait out the front , ,has 2 little flat catches into the deep cup from what i remember . If you sell parts like this & the water pump let me know & i'll find the model # & part # of the cup. THANKS dude & anyone that can answer the MPG question .
Steven Hardy Sorry but i don't sell part's. MPG is about 10% the horse power per hour, so a 10hp is about 1 gallon a hour at full power.I would say your best place too look for the parts is ebay.
Hi Dwayne: Good to hear from you, No water in your area that's no good:( Winter has been a hard one hear, very cold and snowy. You need to tell your son that you only live once and life's too short to not go fishing...:) I will try to send you a P/M with Chucks info or you can just call me.. But i think that You should try to get to Tomahawk.
sounds like you were giving good advice but I just couldn't understand all you were saying with the motor running all the time. A suggestion: in your next video just run the motor when you have to!!!!!!
thank you...your video was very informative...I lost your sound a couple of times, but when you pointed, I followed..
I have found the videos are GREAT ! They were right on the money step by step THANKS

rzacker55@gmail.com
yes the base setting is important especially with this carb as you can get it way off the way the adjuster knob goes on.
What about idle speed knob setting before carb adjustment?@govsux1
Excellent! just what I needed...no nonsense crap just pure information. Quick and honest. :)
Excellent info Ben!!!
1st, Rest in Peace Pepper. Pepper was the star of the show! Clearly, such a great companion. 👍 Onto some Yachting... Since Ben can do this with his eyes closed...lol I'll add to the concept.

Always helpful stuff!!!
Hey Ben, hope your keeping warm this winter, looking foreword to spring here and bending some wrenches on my outboards. :)
I think that Minnesota has had a colder winter then Alaska this year. Good to hear from you and hope you are doing well... Ben

+chrysleroutboarddude You had people posting bad comments about your maintenance videos?
Thanks for the info and videos.
I see you store your paint brush the same place my son keeps mine after he's used them.
lol
Haha
Good to see you back on here again..I missed seeing your videos..Its been cold but no snow..only once this winter..and boy we need the water..if we don't get some soon..will have to fish out of a can..Its been too cold to work out in the garage and I do have a 15 force to fishing up..Son still hasn't run the engine yet..Al work and no play at his end of the world..can you give me the name and phone number of that guy in LA..if he come by to go to Tomahok this year..I got a old green Johnson and a
Great stuff thank you!
Thanks, very helpful
Can you post a close up of the bugger weld on the recoil spring. Thank you
Have a 1984 yamaha 8LN motor. Was running great at WOT one day and then in the middle of a lake just stalled out and would hardly idle. I cleaned the carb, although it wasn't very dirty to begin with, and also I've checked the plugs and they are good as well. Any ideas as to what could be wrong?
Coukd you make a video on how the pull start bendix style gear works and how to replace it. Mine has little spring tension up and down. And the nut likes to loosen on me....
Thanks very helpful!!!do you do work on the side
Not sure if you already did but could you do a vid on a 9 1/2 sea horse carb rebuild?
I have a 74 15hp evinrude. It cranks up every once in a while for a few seconds. I messed with the lean/rich dial, the choke and the throttle but I can’t get it to keep running. New spark plugs. What do you suggest? Do you think I should take out the carburetor and clean it properly?
Hey Chrysler guy!!!
Love your V’s very instructive...
I have a 84 35hp Chrysler that crank on but after 30 sec it dies.
I don’t know what’s going on. What do you think?
Where do you start with the mixture screw? When you build it and put your knob on is the screw all the way in or do you start with it out a couple turns
Every time I back the cam follower behind the cam plate hash line it dies out and doesn't idle do I have to screw in the idle control knob to constantly keep slowest position with the follower lined up with the cam hash ?
It also has the post start that works fine but again I've never started one without the throttle arm so I don't know how to do that either LOL
i have 1991 evinrude 15hp (E15REIA) idles perfect runs perfect but doesnt go any faster after half throttle rebuilt carbs twice, new spark wires,fuel pump, spark plugs, only thing left is coils but one time on the lake it cleared up and ran like a bat out of hell but only did it once. any idea of whats going on? 125psi compression in both cylinders.
I just picked one of these wonderful motors up could I make a video for some help from you +chrysler
I have one of these and it seems that it is very hard to get the throttle control to move once you get close to full speed.The piece that rotates under fly wheel that throttle cable moves seems hard to turn.Any ideas.I have nothing to compare it to.
Also what mix ratio should I use if I just put new rings in the motor
buenas amigo tengo uno parecido y en estos dias se me salio un fusible muy pequeño y ahora no se donde va; usted sabra?
I have a 6 horsepower Johnson do you have any videos on timing adjustment
hey...I just bought a 9.9 hp Johnson 1997 mod. who had been upgraded to 15 hp by taking out the filling...so i was just woundring if i could get more juice/power if i changed the carburetor to a 15 hp carburetor ?? thanks..
Im having an issue with my new to me 15 johnson not running well while trolling at low speed. it seems to flood out and doesnt want to start right away after it dies. the motor runs fantastic but yea, it will flood out and die after trolling for a short time. should I lean it out?? Im a bit confused
ya that is about right. 2-2 1/2
Thanks for that
Also, if the idle knob is taken off can it be install in the wrong position and how do you know if it was, since I am at least the third owner and i could be on in a wrong clocked position?thanks
Hey my adjuster knob fell off and the out board has been stored for a long time so the idle screw is way out of tuning. Do you know about how many rotations it needs to be set form all the way screwed in?
Hi I have a question... Where you had your finger now to the other side when rolling the throttle is a little black plastic part that has a spring... Mine came off and don't know where it goes can u show the motor slow so maybe I can see on ur motor?
Is there a carb needle replacement needed to run at altitude of 5600' ? Just got an Evinrude 15 up and was told it was not set up to run at that high of an altitude
Thanks Dude. I'm thinking i will go about 10 mph @ 250 miles = 25gal. Do you think that sounds correct ? I will start looking at ebay for parts . And thanks again .
Is there a way to run a 90 yamha with out the oil pump alarm to shut of
There's also a high speed screw on the left side of the carb. The shifter side of the engine. Its a fuel mixture screw with a T on the end so you can turn it with your fingers, thats only for high rpm tuning though and unless there's a carb issue you shouldn't have to move that one more than 1/8-1/4 turn in either direction...
Not on this carb
Coco Bolo So what the needle is locked in place?
@@mxracingunlimitedltd7784 Theres no high speed tuning on this carb, only low speed. High speed jet is set, correct.
Hey Ben, love your videos. Wondering if you could answer a question for me? I just bought a 1987 15hp Johnson and it's got it a sticker on it that says 100:1 fuel ratio on it. I asked the person I bought it from and he agreed that is the ratio he used. I read around on the internet and some people say use 50:1 instead. What do you think?
Matthew Olday From what i have learned about this is, OMC recalled the motors with the 100/1 sticker and replaced it with a 50/1 sticker. If it was my motor i would use 50/1 or even more oil. I have a 30hp and a few 6 and 8hp motors that say 100/1 and i use 40/1 in them.
On my chrysler 10hp 107ha the line u reference to line up roller with on the mag plate will only line up with the roller on the throttle control at full throttle. Motor wont' start and pull plugs and flooded. It has good spark both cylinders. Cleaned carb. Is this a timing problem? Any help appreciated.
@chrysleroutboarddude is thisbthe same for the 15hp johnson from 1992?
Hi I have a 1968 6hp I think I have it to rich but have been told if it's leaned to much it can cause engine damage is this true? How do I lean it properly?
How many turns out should the needle be for a baseline on initial start-up after rebuilding the carb? I've heard 2 turns...?
Came across this video. Where is the throttle cam mark at idle?
Where can I find a new low speed idle adjustment screw ?
Could you take a look at my latest video of my 15hp? I zoomed in on the roller position to see if it is correct. My motor is apparently missing the idle speed adjustment screw. There is only a knob with nothing attached. Thanks! You're videos are great!
It looks fine, but i think you will need the idle parts.
Is the first screw that you touched your idle screw?
Hello. I have the exact same motor year and hp. One main issue I have is after I start it with the throttle set to idle. It hesitates and shuts off. Can this be corrected by adjusting the idle on the carb with either of the two screws?
Great video! I have a 1985 15hp Evinrude I've had since new (and it still looks new) and it sat for about 3 years. Cleaned the carb, new plugs, new grease in the low end, new tank and new fuel lines. Idles like it's brand new but once I'm running along and get to about 85-90% of throttle it starts to lunge up and down between 95-100% and down to 75-80%. Up and down....Up and down. I played with the fuel mixture for a while running up and down the river but it doesn't seem to change anything at higher speed. Any ideas would be greatly appreciated. Thanks!
Joshua Auckland It might be time to re clean the carb, sounds like the hi speed jet is dirty. it also might have a vacuum leak at one of the crank shaft seals, or might be a problem with the fuel pump. What do the spark plugs look like?
Hi I subscribe to you I find you extremely talented outboard engineer could you let me know where I can get two under flywheel coils for a Chrysler 20 Hp model No 2033
I’m in the uk I know postage is ridiculous ,
We're you located cause I wish you could get min going
Hey thanks for the video. I have the exact same motor, can you tell me what the knob on the side of the motor is for? Behind the tiller handle on the side is a knob just like the mixture screw on the front, it looks like it affects the throttle somehow? Do you know what it is?
The knob on the right side of the motor is a idle adjuster.
Hi, mine doesn't have the knob how do I know how to adjust it ?
need your help engines giving me troubles. it will start with the choke on and run for approx 2secs then dies a lot of fuel coming out of carburator when squeezing primer bulb.. when i close choke the engine won't start.
Hi C dude I'm working on one of these .. runs great trolls great but when going back to high speed it seems to bog out and catch up after a Lil bit .. almost sounds like it drops a cylinder then kicks back in ...if the roller is out would this cause this effect being the throttle position is slightly out of time .. I know Ill work it out but a Lil help goes a long way .. more familiar with newer stuff Yamaha and Hondas thanks in advance my man .

Try adjusting your fuel settings. If they are off too much gas will get in and the engine won't burn it all and some can get past the rings into the cylinder
Dear Sir, Really Enjoy your Videos, I have been restoring a1964 Sears 14 Ft. Boat and Trailer. I want to keep the Motor I buy to be "period correct" and have found a 1963 Evinrude 6 HP and a Ted Williams 15 HP though I don't know the year. Both engines have been in Storage @ 15 years and was assured they were Both in Good Running Condition. I have not bought one yet but wanted to know what to look for and do you know any Reliable Mechanics in the State of Georgia. Thanks again for Any advice you might can give. Rick Shumpert
sorry to be so offtopic but does any of you know of a way to log back into an Instagram account?
I was dumb lost my password. I appreciate any tips you can give me
@Alex Ernest Instablaster =)
@Kade Dane Thanks for your reply. I got to the site on google and im in the hacking process now.
I see it takes a while so I will get back to you later when my account password hopefully is recovered.
@Kade Dane It did the trick and I actually got access to my account again. I am so happy:D
Thank you so much you saved my ass !
@Alex Ernest You are welcome =)
Hi Ben,
Tony from Australia
Could you show us how you tune up a later model 1996 15 Johnson carby as they are slightly different.
cheers
I will try to get that done the next time i'm working on one.
Hey my 1968 Evinrude sportwin 9.5 idles well but not on slow .. when I go to shift I have to do it quick or it stops it's runs great other then that what would you suggest
Adjust the timing advance a little, or make it a little richer.
Watch you fingers in there!
Boa noite gostei do vídeo.
what year?
first - thanks for taking time to make & post video. I have the same OB (9.9 hp) mine starts and runs fine but......if I back the throttle "all the way down" it will stall. do you think I can just adjust the idle screw?
onenikkione try to get to idle as low as you can then adjust the carb to make it run it's best then repeat
+onenikkione What did you end up doing?
+Austin I got lucky. was able to adjust the air/fuel knob a little and it runs fine
Good video just cant hear you over the motor.
I have a 1980 9.9 Johnson. When I prime the fuel line with the primer bulb, gas is coming out of the carb where the small breather screen is located, on the side of the carb. Is this bad? Engine won't stay running. maybe sucking to much air.
Thanks!!!
Well there are only two ways that would happen #1 needle and seat in the carb is leaking or #2 is the float in the carb is bad.
It's time for a carb rebuild. This is the kit you will need.

Hi great video. I really need some help. I cannot tune my carb. It's 87 15hp late model with black plastic top. I have new throttle roller . All new carb kit. I get engine idle but on gas it Biggs down and dies.
The main jet is plugged.
Make a video a bout 8hp evinrudes
Hi I have about a 2000 15 two stroke and it will not idle. I was curious about the line on the timing plate. I think I heard you say it should line up with carb wheel when at idle. There is a screw on the linkage back by the plugs is this for setting the line? also it seems you can adjust the ramp with that screw in the plastic a few inches from the line. Thanks for any information.
On that motor the 1st thing I would look at is the cylinder head bolts they have a tendency to loosen up over time and cause poor idling.
The 2nd thing I would check is that there is a rubber hose inside the carburetor that feeds the idle Circuit and they will turn to mush. 3rd thing is the top plastic carburetor cover is well known to crack.
So I just got a 9.9 Evinrude that's been pickled it's really clean hasn't run for years but like I said they said it was pickled whatever the hell that supposed to mean LOL I guess it was put away properly but it doesn't have a throttle arm which is okay because I have a sailboat so I steer it with my tiller on my sailboat but it has an electric start and I've never started one without a throttle arm... No I have started a car under the running things using the carburetor and you know throttling it like that but not now bored with an electric start and I'm a bit tired it's been a long long treck and I don't know what the hell I'm doing can anybody help me it would be wonderful thank you
What if the motor isn't running
What fuel/oil mix? Says 100:1 but ive always been told run 50:1 but when I run 50:1 after awhile it fouls plugs out
i run mine on 70:1 i got told to run 50:1 when new depends on how much use my 9.9 sailmaster runs on 100:1 as it runs for 8 hours at low revs.
I've got almost the same motor (25 evinrude). I took it out yesterday and when I left the boat ramp and throttled up, it didn't really do anything. I tried chokin it and still nothin. Then I blocked off the intake into the carb with my fingers and it took off like a rocket. I had to block off about half of the intake. Any clue what would make it run so lean?
Kent Ray Sounds like the "HI speed" jet is plugged, Time to clean the carb.Also check your gas for water.
Thanks man. I did leave the tank unscrewed a little last week when it rained. But on the return trip yesterday the motor ran like it should. So hopefully I just had a little rain water in the tank. Thanks for your quick feedback man!
Kent Ray No problem.
Tengo un motor evinrude 9.9 y el arranque se me descompuso quisiera me ayudes
what is the oil ratio
i currently have a 1976 johnson, it was runing perfectly until someone played with my lean screw and now it idols perfectly fine but when you give it any sort of throttle it just wants to die in gear, could this be I just have to play with the lean screw and put it back so it runs rich again?
That sounds like it is still too lean, or you might have a dirty carb.
I took off my lower unit on my 1979 Johnson 15hp and whole changing the water pump impeller the drive shaft came out of the lower head. Now I cannot seem to install the shaft back without the “ nut “ on the shaft going any further down. It won’t allow for the new plate to sit flush on the head. Any ideas what happened ???? I would rest appreciate if you can help. Thanks
Pull the shaft down(shit into reverse) and it should reach. Ooops...I misread. Did you turn the prop shaft slowly while you try to slip the shaft back in place so it lines up?
Hi I have an old west bend 6 hp motor that only fires for a short while when fuel is added to spark plugs. I’m guessing the carb needs a good cleaning. But I can’t find any how to videos or any information if I’ll need new parts to clean it. If you can get back to me that would be great 👍 or email address for contacting
I have an 91 evinrude 3hp and experiencing the same problem... When I put it into gear it runs rough, the more gas I give, it starts to choke then dies. It seems like the throttle is releasing too much gas or something?? Is the throttle feeding too much gas??
Can you make me a video? so i can see what it is doing.
I'm currently cleaning up one of these motors, 1981 15hp more or less an identical motor, minus the throttle linkage. The motor i have has never idled according to the past owner and i couldn't make it idle either. I just rebuilt the carb but it wasn't all that dirty. It's winter here so I can't test it, but could you maybe let me know exactly what screw you were referring to? Mine is missing the idle knob on the left side of the motor but i'm told that doesn't have much effect
Well 1st off you will need that idle adjust knob, without it you will not be able to set the minimum engine speed. Now if i remember the 1981 does not have a throttle lash adjustment screw. When it warms back up again make a video of what it is doing and i will help all i can.
chrysleroutboarddude
appreciate the response, i talked to a few guys and they said the idle knob wouldn't make a huge difference and that it should idle without it, i actually found the retaining pin and the plastic knob inside the motor, the knob was gone though..the screw it looks like you're pointing to, on my motor is an allan key head on a piece of plastic, it doesn't appear to have much effect on anything? as the motor is sitting in the dining room i could email or post a picture thanks again
chrysleroutboarddude
imgur.com/sg4lKhg
this is the screw only screw in that area, it's attached to the throttle, though the 1981 doesn't have a throttle cable it uses the gear teeth (terrible design) this screw doesn't really appear to do anything it's just screwed into plastic
ryanbreeze Well the idle is set with a combination of timing and throttle plate position and fuel mixture. What that screw does is set the position of the throttle plate in the carb and when you open the throttle on the carb with the engine at idle it will lean out the fuel mixture. so that is why you have a low speed idle mixture needle. The idle adjustment knob sets the timing, and if you can't set the timing there is no way to get the throttle cracking screw set correctly. For a starting point close the idle mixture needle all the way, then open it 4 turns, then set the throttle cracking screw so that the throttle plate just starts to open when the roller lines up with the line on the mag plate, then set the idle adjust so the timing will not go lower then the 1st line on the mag plate. Start the motor let it warm up then you will be able to fine tune it by adjusting the cracking screw and the fuel mixture needle. Then and only then you can set the lowest idle with the adjustment knob on the side of the motor.
chrysleroutboarddude
i really appeciate the responses, were you able to look at the picture i posted above to see if that'sthe throttle cracking screw you're referring to? i took a pic of it, as it's out of my motor right now, just doesn't seem like it does any actual adjusting. (sorry very new to this, first outboard)
That sounds like it is time for a carb rebuild. the needle and seat are leaking.
chrysleroutboarddude - I just bought the same motor in your video. I also have the same problem, being a broken idle stop knob. A new Idle adjustment plastic knob & retaining ring from Amazon, $36.00 is on its way. My question is, why do I need this, on my previous motors mostly Mercury, there was no such thing, you would turn the throttle to start and start the motor, then when stopping I would turn the throttle down and shift to neutral. Please reply.
You dont have to have it if it idles fine and you dont need to adjust it for trolling. Thats all its for....allows you raise/lower idle without adjusting anything on the carb. I know this is old post but just in case you never got an answer.
Can you do some more repair videos it would be awesome
If it is hesitates it probably needs to be richer on the low speed.
how far should you have to twist throttle in order to start?I asume this determines on the one adjustment screw you talked about.Also, if I have the throttle twisted all the way off should that little roller be hitting or just barely touching the piece it rides on?My roller is pretty far away from the piece it rides on, so I have to twist throttle pretty far in order to start to open throttle to start.
Adjuster the rollers screws until it touches
Right by the coil but the right side
So I checked the jets, they're brand new with nothin cloggin em. Only thing I can think of is a vacuum leak in the carb somewhere. You got any other suggestions?
Just checked the plugs... Put brand new plugs in before I took it out last and the bottom plug is fouled. There's fuel from the pump though. I'm stumped
Kent Ray Can you make me a video So i can see and hear what it is doing?
I can make a video but I highly doubt you'll be able to hear it. It only happens in gear and on the water.
Kent Ray Well we can try
I have a 1979 Chrysler 7.5 that I have been trying to get running, and i have done everything the manual says to do, but the engine will only stay running for about 3 seconds before it dies again. It wants choke on to start but immediately wants it off to run. There have been a couple of time when it ran fine for several minutes and especially well at full throttle, but now I cant keep it running. Ive verified compression with a gauge (100psi on both cylinders), replaced the fuel lines, fuel pump, cleaned the carb and adjusted the float and mixture screw, adjusted the stator control link and throttle cam follower, gaped the plugs all per the manuals instructions. It seems like a fuel problem to me but I don't know what else to try! you seem to have great success with these motors, and was curious if you had ever run into this?
Justin Boyce Can you make me a video? Is it hard starting? I have seen a few of them with broking reed valves.
What city are you located in? Do you offer your marine repair services to the public?
I am in Oak Grove Minnesota and yes I work on Chrysler and Chrysler made motors and OMC Johnson and Evinrude up to 35hp
I just bought a 85 15hp evinrude. When it's cold and it first starts up the rpms go crazy (I'm no mechanic). Just when I think I'm going to become a human drone, it goes to "normal" idle and runs smoothly. But when in forward I can't go more than 8mph in a 14ft smokercraft. It seems like I should be able to open that up and get about twice the speed. I suspect the butterfly valve is not opening all the way. Anyone have ideas? Please go easy on me. Thank you!
I have the same exact problem have you fixed it if so how did you?
@@hippomicheo484 one cylinder wasn't firing. thought I had it fixed. new coil resolved. but now the thermostat is bad and it's located way down below the rear cowling, so I can't get to it. gave up. sorry.
Witch spark plugs do you use?
henning sellevoll I use Champion most of the time.
what type? i have two mounted on the engine. they are called champion RN3C and champion L77JC4. Sorry for bad English :)
The l77jc4
You need a book when you adjust the carburetor on that motor the throttle needs to be closed tight there is no other way to adjust it properly read a Johnson service manual and it will
Great video dude , I started out to ask you or anyone what the MPG of a 9.9 johnson ? An EDUCATED GUESS ? , for a no gas station for 250 statute miles trip i'm taking 11-22-14 ,dose anyone know ? BUT NOW i see you are the chrysler outboard dude you might have parts i need for a 3.6 chrysler , I need a pull cord ass, it comes strait out the front , ,has 2 little flat catches into the deep cup from what i remember . If you sell parts like this & the water pump let me know & i'll find the model # & part # of the cup. THANKS dude & anyone that can answer the MPG question .
Steven Hardy Sorry but i don't sell part's. MPG is about 10% the horse power per hour, so a 10hp is about 1 gallon a hour at full power.I would say your best place too look for the parts is ebay.
vohager 3.2 hp I will give him..think the Johnson 5 hp just needs the points cleaned.
Hi Dwayne: Good to hear from you, No water in your area that's no good:( Winter has been a hard one hear, very cold and snowy. You need to tell your son that you only live once and life's too short to not go fishing...:) I will try to send you a P/M with Chucks info or you can just call me.. But i think that You should try to get to Tomahawk.
Jwanat
You could have shown us this without the noisy motor running.
NEVER PUT YOUR FINGERS NEAR THE FLY WHEEL
sounds like you were giving good advice but I just couldn't understand all you were saying with the motor running all the time. A suggestion: in your next video just run the motor when you have to!!!!!!
