Thanks for the video. Small learning curve makes it quite easy after the first attempt. Had a gummed up carb on a 6hp Tohatsu, despite draining the bowl over winter. Cleaned the main jet with a steel wire strand, which allowed it to start. But could not idle. As there is no jet to clean, but a circuit, I left it soaking in White Spirit. Morning after resulted in a telltale mucus residue at the bottom of the container. Voilá, runs like new.
IT WORKED !!. it wasnt dirty at all but i cleaned it anyway , put it back and started right up. I had some questions about the black plug that fell out...didnt know where it went at first. i saw your video and it was visible...Thanks again.
agree with below- would love to see how you rebuild this carb- having the same issue on a 3.5hp version of this motor, still won't idle right. hope you do more videos soon!
Sounds like my issue. Motor only has a few hours on it and it's an 05 model. Ain't been cranked since 05. I can only get it to run on starter fluid in the carb right now. Guess I'ma bout to do what you did an then watch your next video on how to rebuild it. Mine is a Yamaha 4hp 4 stroke but it should be very similar
I had this exact problem on a Tohatsu 5HP-Had to rebuild carb with new jets.Ran engine with TruFuel before storage and filled the gas tank with non-ethanol gas.Some marinas have non ethanol fuel available.
I came up with a crazy idea years ago. If it has a carburetor don’t use fuel with ethanol, ever. You can get premium fuel that has ethanol so I only use 91 octane ethanol free gas. Also pump some into a jerry can or your car first to make sure the ethanol is out of the line. If you are too cheap for this then don’t use anything with a carburetor because it will cost you more in the long run anyway.
what are the two brass inlets on top of the carbyfor? my problem is, when I prime the fuel bowl ,fuel pours out of those two inlets that don't seem to be be there for any particular reason LES
I have a 2003 15 hp Mercury 4 stroke carburetor problem,when i pump fuel bulb on hose to put gas to carburetor the float will not shut off fuel to carb,I put new float and needle valve in carb but still same problem.
My motor would start but die out after a short amount of time. Took it to repair guy who said gunk in carb . Ching-ching 150 bucks. Started doing the same thing not long after. Would run for awhile then konk out. Seemed like it's just not getting fuel to the carb. Squeeze ball would soften. Tried putting fuel tank at a higher elevation which helped a little, but still konked out. Fuel pump maybe? Thanks.
Good vid ! Question i have a 2.5 4 stroker with a brand new carb and it runs fine but ut leaks crazy amont of fuke through the vent hoses that are by the impeller hose why would it do that i mean i doubt the floats stuck or anything like that could it be the air flow screw to tight or loose ?
Mr. Manley if any found how to take that float out... without breaking nothing... i’m really interested. I already broke one. And scrap the carb. Here very expensive to replace. Thank
I really like your videos as i have learned a lot from them. I enjoy rehabilitating old Johnson Evinrude motors. Although I am at my whits end on a 1972 25 hp model 25R72R. i have changed out the powerhead, lower unit w/3 eared gears, seals, impeller, carb kit and even a rebuilt carb a "professional" installed kit. Now it acts like the carb is clogged and is dripping gas from what appears like its from the float bowl and does it with either carb i have for it. And the spark plugs seem to be dry. Also just replaced leaf valve gaskets as internal one was leaking. water into top cylinder. I know thats alot but any ideas and suggestions? ? Thank You, Kentucky Poor Boy
Great video ...I have a 4hp tohatsu and rin perfect for hours and then it I have to dock and put motor up I tilt up lean to handle ,when going again its tarts to sputter and eventually stalls and spit out fuel from the over flow ,I have had the carb cleaned and even the float valve replaced and it still happens and normally I have to let it sit for a while and then eventually it will start ,sometimes I can get it to go by putting in full throttle ....could it be that the float valve is just getting stuck and gas over flows ..I bought it used 4 years ago and haven't been able to resolve this otherwise it runs great.
@@jessiecasanada8158 no i have asked some questions at another dealer and he said it might need a new carb he showed me a box full of old carbs that they have replaced on small mercury and tohutso which makes mercury
I have a 1998 4.0 2 stroke Mercury engine I open up the carburetor I didn't find No Junk in it at all my engine has a good spark good compression but for some reason it turns on and it cuts off right away any idea but is really hard to get on to as well like if the fule not going into the system
What I think is politicians who promoted to use alcohol should be condemn to buy you a new engine and clean thousands of carburators all over their countries.
hello maybe you can help me i have a four stoke mercury 4HP more than 1 year i didn't star it. so when i try to start it. its nothing cannot start what should i do? i use only the internal fuel tank should i change the fuel? and check or clean the carborator? thanks
both of them is correctly. You must be carefully to check float position, because it's ("float" ) always changing to the adjustment. you are making the adjustment yourself.
Hi James, i have just bought a mercury 3.3 2 stroke... starts and runs very well, except i do notice that if tilt the engine up.. without turning off the valve and draining the remaining fuel in the carb, fuel starts to spill from the carb and in to my boat. is this normal? thanks D
Great video. Just had my carb rebuilt, motor started first pull and ran great. Second time, won't start at all. Fuel shoots out of the brass nipple on the top of the carb. Any ideas?
+patrick evans probably some varnish in the fuel pump, but the passages are not as small as in the carb, so the flow of clean gas is usually enough to keep it functioning properly.
Hello, I have a Nissan 18hp 2 stroke, my luck with 2 strokes and carbs hasnt been good, 4 strokes im good... I think it needs some cleaning... When accelerating it stutters/ hesitates then runs like a screaming demon... all speeds are fine at steady, but if you go from just off idle to wot itll stutter for about 15 seconds then go, the whole time slowly revving, just not smoothly... Plugs good, new coils because the coil went bad last year.. It has been through several tanks of fuel now, and hasnt cleared of this issue... I havent found a place for nissan carb parts though... is it tohatsu as well?
took carb apart last night, clean as a surgeons tools... played with fuel mix screw... only found one though, thought most 2 strokes had a high and low? Thanks for even responding... Im a 20 year car / diesel mech, 2 strokes befuddle me some
Thanks for responding... I took carb apart, float adjusted properly, all jets clear etc, played with the only mixture screw I found until it sounded better, we shall see once I put it on the water.

HollywoodtoVegas.com hi. Where does that black plug go? I opened my carb and can't figure out where. Thanks.
Thanks for this video, following your principles, I managed to fix my Tohatsu 3.5 2-stroke. Nice one.
agree with below- would love to see how you rebuild this carb- having the same issue on a 3.5hp version of this motor, still won't idle right. hope you do more videos soon!
How come you never posted video showing how to rebuild this carburetor?
Excellent. Really easy to understand. Thanks. Vic

You were right. She's running, now I gotta get the idle set, and figure out why it's not peeing
awesome video...taking my motor out and trying this.
Thanks
Where is the video of rebuilding the carb? Great video. I have the exact same model and I think I have the problem mentioned above
This is the same thing for the Tohatsu 5hp so yo should put it in the title
+Joel Flores Great feedback. Thank you.
what are the two brass inlets on top of the carbyfor? my problem is, when I prime the fuel bowl ,fuel pours out of those two inlets that don't seem to be be there for any particular reason LES
Do you have the video of the cleaning of the carburetor? I couldn't find it on your channel. Thanks!
Thanks for the video. Do you have a video on how to rebuild the float? Cheers
really helpful video thanks I just like it
spot on
I have a 2003 15 hp Mercury 4 stroke carburetor problem,when i pump fuel bulb on hose to put gas to carburetor the float will not shut off fuel to carb,I put new float and needle valve in carb but still same problem.

Thanks.
Disconnect the fuel hose that's attached to the carb, and pull the starter cable. See if any fuel comes out. If it does, then your pump is fine.
Good vid ! Question i have a 2.5 4 stroker with a brand new carb and it runs fine but ut leaks crazy amont of fuke through the vent hoses that are by the impeller hose why would it do that i mean i doubt the floats stuck or anything like that could it be the air flow screw to tight or loose ?
Did you ever make a tube - How to take the float out?
Mr. Manley if any found how to take that float out... without breaking nothing... i’m really interested. I already broke one. And scrap the carb. Here very expensive to replace. Thank

Great video ...I have a 4hp tohatsu and rin perfect for hours and then it I have to dock and put motor up I tilt up lean to handle ,when going again its tarts to sputter and eventually stalls and spit out fuel from the over flow ,I have had the carb cleaned and even the float valve replaced and it still happens and normally I have to let it sit for a while and then eventually it will start ,sometimes I can get it to go by putting in full throttle ....could it be that the float valve is just getting stuck and gas over flows ..I bought it used 4 years ago and haven't been able to resolve this otherwise it runs great.
I am having the same problem..it starts right away but if I stop the engine it just won't restart right away..have you done something different?
@@jessiecasanada8158 no i have asked some questions at another dealer and he said it might need a new carb he showed me a box full of old carbs that they have replaced on small mercury and tohutso which makes mercury
What make are the carbs on this engine? Yamaha and Honda use Kehin, Mikuni and Nikki carbs, but I don't see any Carb stamping on my 2018 Tohatsu 6hp.
I have a 1998 4.0 2 stroke Mercury engine I open up the carburetor I didn't find No Junk in it at all my engine has a good spark good compression but for some reason it turns on and it cuts off right away any idea but is really hard to get on to as well like if the fule not going into the system
Guys this smal engines have an air filter.....for example an parsun 5 hp should have one?
Did you have to adjust the idle screw?
What I think is politicians who promoted to use alcohol should be condemn to buy you a new engine and clean thousands of carburators all over their countries.

Great video. Just had my carb rebuilt, motor started first pull and ran great. Second time, won't start at all. Fuel shoots out of the brass nipple on the top of the carb. Any ideas?
Sounds like the float valve isn't cutting off fuel flow when the carb gets full. Floods the engine, and shoots out the overflow port.
I've got a 2016 Tohatsu 5hp that suddenly increases RPM when shifted into neutral. Any thoughts?
Hey, I have a 1999 Force by Mercury 40hp and my carburetor get cold and sweat. Also some times it leaks gasoline. Any suggestions?
What is the best small outboard for doing repair work.
OWL i suggest the 5 and 6 hp Mercury. They broke often so you gonna have to repair it often.
i wonder what the inside of the fuel pump looks like? same as the inside of fuel bowl???
+patrick evans probably some varnish in the fuel pump, but the passages are not as small as in the carb, so the flow of clean gas is usually enough to keep it functioning properly.
too bad your mic was muted for half the video.....the important part?
Sounds like Kevin costner
Cant you just run non ethanol gas to clean it up.

There is a good chance that your carburetor needs cleaning and mixture settings to be adjusted.

Ethanol is the enemy of the two stroke, quit using it and enjoy your boat anytime you want.
where the rebuild vid?
