He talks all the way through the video and that’s great!! Goes slow and step by step explaining all the way!!
Glad you liked it!
Dangar Marine thank you for this video. It was EXTREMELY INSTRUMENTAL in me rebuilding the carbs on a 1985 Johnson 60hp. I am by no means a mechanic, but I literally could NOT have done it without your video. I can't thank you enough... Who knows how much $$$ you saved me. Keep up the great videos!!!
You're welcome Brandon, glad to have been able to help. :)
Lol
Found the problem, it was timing, the spring mechanism kept moving around. Carburetor works great
I've been playing with all mechanical things since I could walk and I'm so grateful for doing what you do mate I've learnt so much
Quick tip for tools to work on Carbs with. Gunsmith screw driver/tools sets are great for working on sensitive brass parts like Carb Jets. The screwdriver bits are designed differently than normal screwdrivers... normal screwdriver flat head bits are tapered, Gunsmith flat heads have an even thickness shaft so are less likely skip out of the slot and damage the soft brass or other screws that hold the Carb together. Also, these sets (not advertising for them but the one I have is an 89 piece set from Wheeler Engineering) offer a lot of bit size choices so you can find the exact bit that fits snug and is correct width to fit into whatever Jet/screw you need and helps to prevent damage to them. Thanks for your videos, they have been very helpful! Watched your other videos on Carb tuning and helped me get my work boat back to working order and working quicker than if I had to go to a mechanic, thanks a lot!
Hey Martin, great tip about the screwdrivers, I'll check them out.
Take a photo of what you're dismantling as this helps when putting complex parts back together. If you are leaving the job for a couple of days its wise to put things back together hand tight. Stu your videos are great. Thanks for sharing your knowledge.
You're welcome mate. Photos sure do help!
Used this to Rebuild carburetor x 2 ,55 evinrude commercial . Put it in the water yesterday 👌 this guys a legend 👍
Thank you Stu, really help me fix up my old Johnson 25hp after it flatlined. Your videos are so helpful.
Excellent video! I bought a used Johnson 25hp outboard with electric start. It ran terribly! Decided to rebuild the carb and noticed someone had installed the float up side down! It was harder removing the starter to access the carb nut than it was rebuilding the carb! Thanks for a great video.
Omg you're helpful. Got a running, new to me, old boat with an even older motor. These videos give me peace of mind that, with your instruction, I'll be able to fix things that may come up ohn the future, and perform done preventative maintenance.
Hahaha. 26 seconds into the video and I’m already lost. 😄 Starting with “I’ve already removed the...” probably wasn’t the beginning I was hoping for. 😬😂
Hey Danger, I really appreciate the step by step. My Johnson 25hp stalls after I power down when arriving to dock. One marina just cleaned the carb but it still does the same thing. I opened up the fuel pump like in your video and discovered the same issues, broken cap and o-ring. Thanks for you input. Cheers
Your video is one of the best I've ever watched. Your step by step instructions were very easy to understand.
Wow, thank you!
You do great videos Stu. Thank you for all the work you put in with these videos. You take the scare out of starting those bigger jobs. I got my junk 150 Force motor going with all the general information from your videos
Thanks Rick. Great to hear you got your motor running again!
Thanks for the video, I just rebuilt the carb on my 30hp Johnson and now it's running great. Appreciate the walk though!
Great video. I have a request, could you make a video about symptoms. Like you'll know your carb needs cleaning if....or your float needs adjusted if ....
Thanks for all the helpful content.
I can see removing the starter for convenience. But do you have to remove the entire mounting assembly ??? Great video though, very easy to follow.
Thanks dangar ! Couldn’t do it without your knowledge! You are a great instructor!
Glad to help
Thanks for this: it was a great help when I did my Johnson 50 carbs.
That video was super useful! Thanks for walking through everything slowly and explaining thoroughly!
Thanks for all the great videos. I am trying to get a 1975 25 hp Johnson that was run in salt water. It has been setting up for 25 years and I am learning a lot from you. Thanks again
You're welcome. :)
One of the best videos ever. Your explanation is perfect. Thank you very much.
This is exactly the video I needed to get my engine running! Thank you!!!
Can you please help me i have jhonson 30hp pls help me want start again before all good but we make like a hour driving and then just stop and we cant start again
Thanks so much, was rebuilding my carb and never would have seen the main jet on the bottom of the bowl if not for your vid!
"Hollow Ground" screwdriver tips. they will prevent brass or aluminum distortion , the flat blade driver will almost always mark up and nick the fittings or fasteners.......
Great video, you dumbed it down perfectly for me.
I almost can't wait till my carbs need cleaning so I can try it. I might have to put sugar in my own gas tank.
I'm getting into a knew hobi learning everything obout outboards thankyou dangar you bring me great knowledge.
Only thing I would add is on older carbs, check the butterfly shaft for excessive play before you order any parts. Most of the butterfly shafts run 'plain bearing' in the body of the carb and once they get to a loose fit the carb is often considered 'worn out. No one sells a bush kit for these carbs, but any decent machinist can make a set of bushes and ream the carb body to fit the bushes and so return the butterfly shaft to a decent air tight seal.
Yes, once those shafts get flogged out they can become another vacuum leak.
Nice video and work. Do you know what the 2 numbers inside carb represent? Located just below emulsion tube, one number above the other. 334 375. A different carb that looks identical has 332, 562. I’m trying a different eBay carb on my 28spl.
Thank you.
YOU ARE AMAZING !!! Thank you for all of your very helpful videos.....keep up the great work
You are so welcome!
I like to clean the carburetors with an ultrasonic cleaner. A little bit of Degreaser some water turn the heater on right it for a few minutes and it usually comes up good.
I'd like to play with an ultrasonic carb cleaner one day.
This video is going to be my tutor through the process this coming weekend. I have a 78 35hp Johnson with the same parts number. Thanks very much for this video. I’ll be filming a bit of it and reference this video.
You're welcome mate.
Yes, back in 78 the engine HP was rated at the flywheel. This engine is around a 1993 or so that this guy is working on, and by then they rated it at the propshaft. Since about 5hp is lost between the flywheel and the propshaft, a 35 in 1978 is the same engine as a 30 in 1993 because your 78 only has about 30 propshaft horsepower.
Thanks for your experience man did what you said and my envinrude 15hp is working like New thanks all the way from the Caribbean Trinidad
Glad to hear it is working well again. Would love to visit Trinidad one day! :)
Excellent training for my two Johnson 40 carbs. Thanks for sharing!
Awesome video Stu.
I bought an Evinrude 30hp last week, it ran fine for the 3hr cruise home but now has a rough idle I suspect from picking up crud from the bottom of the tank (it got choppy 20minutes from home) first thing to do is is clean the carb (and tank, filter, plugs etc etc) but atleast now I have a comprehensive guide as to what I'm doing.
Excellent video and well presented. the mixture screw on my 30hp Evinrude required 5 1/2 revolutions out before engine would run sweet. thanks Stu
Thanks mate. Interesting to hear where yours needed to be at.
EXCELLENT VIDIO, in regard to changing the jets for altitude ,who would provide that info.?At 4000 ft. what size jets are recommended.
In regards to the idle mixture screw, what would be the best way to know where the screw should be set?
Thanks for this. My 1986 force has fuel running out of the bottom two carbs. This will help a lot once I get the kits in the mail.
Anybody know how to get the needle seat out and back in these carbs
Now that I own a 33 year old outboard I'm your biggest fan.
That's a good run for an outboard!
@@DangarMarine Yes I reckon she's got another 33 years in her no problem ;)
Any marine mechanic that makes a how-to video with a bottle of beer on the table with him has my business.
Thanks for another helpful video , my 30hp is almost ready for a water run cheers
You're welcome Andrew, good luck with the first run!
Video deserves 1 million likes....
Thanks mate.
love your work stu, especially with a brewskie next to it
Checking in from Detroit Michigan USA suburb! Great vid mate. Learned a lot about carbs and I am looking to rebuild my first carburetor soon!!
Good luck!
Amazing amount of knowledge, brilliant!
You just might have given me the resources to fix my old 70’s 55hp Johnson 😅👌
I’ve learnt so much from this guy.
Tx for the input. Your vids are well made and very helpful.
Great job ..can't wait till it runs...James in Houston, Texas
Thanks James, I'm looking forward to getting this one up and running too.
Thank you Stu, Good and fun educational timekilling while waiting for spring!
Thanks Michael. Not long to go now!
I know this thread is old I purchased a 1986 30hp Johnson with manual choke but the bowl on the bottom of the carb has a screw with a nut Im not sure where the bigger hose that comes off the left side of the choke goes any help would be great.
Great video Stu. You know there is something nice I find in servicing carbs. Whilst I know a lot of injection set ups are becoming mainstream I like the idea of being more "part of the process ". Injection is a little less romantic. If that makes any sense. Or Maybe I should just put the merlot down....
John Wills - anytime you would like to come over and get “romantic” with the six carbs on my 250 Johnson, feel free. They are due for a rebuild ha
Brother you saved me today out in the water thank you so much 💯💯
You're welcome. :)
I've got a 81 35 evinrude... the float bowl is nowhere near being level with the body. Its resting on the needle but it is flat with the body, 1/8 inch above the body. Should I bend it down. ?
I just clean the carbs on Johnson 60 1991 and when I start it up it reves up like a dirt bike, full throttle? I didn't adjust my floats but I think they were low like yours were until you leveled it, could that be my problem?
Great video as always mate.
I am still scared shiteless starting this on my Johnson 90 V4 - 4 times the opportunity for screwup.. 😳.
Great informative video! I can't wait for it to warm up on my side of the pond, cold here in New Jersey US, thanks again.
I left NJ (Hopatcong) 3 yrs ago. where ya from?
southern new jersey Cape May.
I was up top. Cheers
john I need help my Johnson. 90 hp 2005 rpm max is 2000 and it will bog down when I accelerate please help
your videos are very informitive keep up the good service!
Thanks mate, glad they are helpful.
Okay Evinrude 50hp cleaned the carbs now I discovered that lower carb not getting enough fuel, tried blowing into fuel line with carb upside down can Barley blow any air in, top carb I can blow into it easily so I no the float works great, what could be the issue? I took it apart all seem normal. The top carb I can hear the float flaping around the lower carb can't get much sound out of it, Could the float be getting stuck inside the bowl?
Hi how i can i remove the jet in the center of carburetor on a 9.9 i remove the one jet but seem like one down underneath but the grove for the flat top screwdriver to remove it is worn
That was the cleanest carburetor bowel I have ever seen. Now in my world the pivot pin has corrosion on it and when you try to push it out the tower that holds it snaps off and you have to buy another carburetor anyway.
So true...my bowels are never clean
Muchas gracias, me sirvió mucho, Saludos desde Paraguay
Seems related, pls help. Every diagram I have found shows a core plug instead of a screen on this carburetor side vent. My carburetor has a screen instead. The rebuild kit I bought has core plugs that would fit this but no screens. In fact no website including Johnson/Evinrude sells these screens. There is a big difference between core plugs and screens. The opposite of the carb has a similar vent with a factory installed screen. Part number 4 on this diagram is what I’m talking about. Why the discrepancy?
I have a Eslene 28 spl 1992
Dangar Help!! I've got a 2001 25HP Evinrude, 4 stroke, 3 cyl. Engine oil temp was going off, replaced sensor and also new water pump because it was worn. Now when running water enters all three carbs???
Oil temp light still comes on but takes much longer. Why is water flowing into carbs?
If Cracked Block, how best to check?
Like the way you do your vids...you have helped me a bunch.your vids sre easier to follow than most
Glad to help
I have the j140txcdc with plastic carbs and the black emulsion tubes are crumbling and mostly gone. No manuals show this part! Do you have any suggestions to fix this without buying new carbs? Thanks
Great video. I have nearly the same motor and this has demystified a lot of the subtle tuning problems with mine. Thanks again.
I have a question I got a Yamaha 115 2 stroke you can run like 30 or 35 all day long you open it up and it dies let it set for a minute and it will restart you have any idea what's going on I would appreciate any help at all
Got a Johnson j150eleom. Gas pours out of top left carb while running.not a gasket leaking I beleive its the tube that shoots gas in the carb.any suggestions?
Have a Johnson 6.5 and it does run while the primer is on. When turned off it shutdown. What can be the problem?
Really good video step by step. Thanks a lot . And for those 99 dislikes they must be democrates. Just saying.
I bought the right repair kit for my engine but only realised when disassembling that it doesn't have the original carby on it. Managed to get by though however there is screw hole in the engine that is exposed which would have been filled with a screw from the original carby. Anyone know what I can do about this extra screw hole?
How's it going today I have a 1990 Johnson 40hp ant there are two mixture screws one on each carb behind the throttle linkage any idea what factory specs are on them. Thank u
This is not about the carb. But I have a 35hp 1976 Johnson outboard I would like to know if you can tell me where I would install a pee tab on it?
Hi im working on a 9.9 evinrude it wont idle and i clean carburetor but made noom difference i need choke to get itvto started again some time it will still if u hive it throttle any help be appreciated
I have a 1979 evinrude 35 hp, do you have a video covering the silencer box removal? I am trying to replace the starter and I can't get to the front screw.
What if my carb doesn't have small metal clip that connect float needle to float? The float needle doesnt even have a space for clip to slide on. It's smooth on the outside side. Does the float just touch it and doesnt need to be clipped?
Best rebuild video I've seen right to the point! 👉
Is there anyway I can shoot some cleaner into the carb jets while they are still installed on my 2-stroke Johnson 150 V6? Haven’t ran it in 2 years and I’m worried about starting it and the jets not lubricating the cylinders.
I have a 1969 Johnson outboard 2 stroke it runs good but it hesitate off idle to going full throttle. Should I just rebuild the carburetor or just clean the inside out or just the fuel bowl? That's again Kyle
I would suggest cleaning off the old gasket between carb and block BEFORE disassembling and cleaning the carb.
If it’s possible to be more impressed each video, even after 20 videos and some 3x (so far)…
Then rest assured I am. Some people are a whale, or a or dolphin but this bloke is my marine spirit animal

Hi, I have an 1997 Evinrude 8 Hp 2 stroke. I'm having trouble starting to cold. I also changed the piston rings (the cillinder compression was 80 psi) , the spark plugs, I cleaned its carburetor and it still doesn't start. It starts very very hard only with the shock pulled and the acceleration at maximum. After starting for the first time this way, the following starts are very easy. Can you advise me what to do? Thank you.
So I rebuilt my carbs on my Evinrude 40hp (1995) cheap enought for kit($12) my problem is the seat. The new one seems to big,and I don't want to force it because of the soft metal...so I reinstalled the old one. When I squeeze the primer bulb, gas comes out of the top of the bottom carb...not seating...
Should mention when adjusting the float not to use the needle and seat to bend the float higher. It is very tempting to just jam it against the seat to bend upwards.
Yes indeed. I find holding the float up off the seat a bit helps with that but a good point well worth mentioning.
Imperial fasteners, gotta love 1890!
I have an older boat(1988 omc cobra 4 cylinder) and am switching to electric choke but am wondering if the hot wire should go to a ballas resistor?
Hi, I have an issue with a 110 Johnson j110tlcur, it has been serviced VRO disabled, issue is it runs smooth at first, taking a minute to go full speed on a 17.11 bass boat, then on the next start it takes longer to rev up and so on... taking apart carbs after the run, we find like an oil plaster on carb throats, what can be causing this issue?
I just picked up a tracker boat with a 93 Evinrude 40 hp. I did a cold compression test before doing a lake test & compression on top cylinder was 150 & bottom was 149. Did fine at the lake, but idles a little low & takes a little bit to get warmed up. Do those compression numbers seem too high? I trust my gauge but just seems high to me now that i think about it. Motor appears ot be pretty low hours & not used much over the Years
I rebuilt the carbs on my Honda BF90A and it turned out that some of the low-speed emulsion tubes were cracked! These cracks can be difficult to see, and sometimes are only apparent when you blow carb cleaner through the tube (the cleaner blows out the side of the tube through the crack). So it's probably best with these old Hondas to replace the emulsion tubes.
You certainly have to look very closely at some parts to make sure there is nothing wrong with them. It's amazing how quickly a small crack in the wrong place can have a motor running very badly.
That’s nuts, that a company recognized for quality and technology would put a component in a recreational product with such a delicate failure mode. I was a supplier to Honda. Their engineers thought they were Gods. Gods my ass, my engineers found and fixed their screw ups. No charge, it was like we should not let them make mistakes. What a rotten business. Retired many years ago.
Hey I have a johnson 15 carburetor not exactly sure the year but the bottom bowl is black plastic. I messed up the jet that goes in the middle of the carburetor that had one of those metal caps over the end. I need a new jet but I am unable to find one anywhere. The carburetor is discontinued. Do you know where I can get a jet. I think its the main jet but not sure. Its like 2 Inches long and looks to be like 3/32" round. Any help would be appreciated thanks.
Why don't you post no more
where did you get the float gauge in how do I find one
Hay stew i have a question i got a 25 hp 1985 johnson i rebuilt the carb and i noticed this carb has a manual fuel primer on the front of the motor. If you prime it then leave the primer knob out a bit it will run looks to be pulling fuel through the top little line to get it to run or idel is this Normal ???
Good work and thanks for spreading your knowledge
I have gas leaking through my carburetor through 91 Johnson 25hp, help. Thanks
Can you tell me what the bearing that is in the side of the bowl is for because mine fell out. I put it back in and sealed it up with JB weld.
When I set my float to 28 mm, the float seems to rest on the bottom of the bowl. Is that a problem?
great videos keep it up thanks glad im in fresh water only
ere is the mixture screw on the carb...i cannot find it.
I’ve been working on a 1984 Evinrude 35 hp I’ve been thru the fuel system twice rebuilt the fuel pump carb looked like someone had already been thru it good compression and appears good spark on cranking it will start and run for about 20 seconds and die float bowl is full of fuel I don’t know maybe it’s running to rich but it will only start after I hit the primer I’d say it’s starving for fuel or it’s losing spark
Do you have a carburetor rebuild video for a 1998 E6 REC Evinrude 6 hp outboard? Thank you.
