Yamaha 3HP two-stroke Carburettor Clean Tutorial 

Thanks for a good tutorial. I might add that interdental brushes are great for clearing the smallest jets holes (you won't believe it but they'll go in). And it's a 3hp, not 2. There's also a filter in the tank that could be clogged if not enough power (very rare). Very good engine this. Easy to pull and super reliable. No wonder Yamaha gave it a name and not just a number.

Great tutorial , thank you

Top lad. Thanks!

Forgot to say the reason I was here was that my Malta wouldn't start after winter storage and checked to see if I'd missed something. After some fiddling it was clear the float needle didn't move, but after a good rub with a cotton bud and carb cleaner liquid on the needle's sides and inside the needle cylinder, it moved freely again and all was well. Btw, I noticed my float sits at quite an angle and not around 90º to the jets as I was expecting and what it looks like from this video, but that's obviously how it's supposed to be as it runs perfectly. Maybe it's an earlier or later model with different specs. I will also not run the engine out of fuel again as I did winterizing this time, as the corrosion / crud issue jamming my float needle was maybe because it was sitting dry. I've heard somewhere one could run it extra oil rich for the last run before winter storage so maybe the idea is to everything a good coating of oil to prevent situations like stuck needle.

Thank you, just rebooted my own Malta with your tutorial!!

Cheers for that, I have the same engine. Love it, was out for a few hours the other day. Ran over a bit of seaweed and the engine was not running properly then it stopped. Checked the impeller yesterday found a piece of the old impeller blade in the water intake. Thought it was it. No, still dieing when I give it throttle. I think I will have a go at the carburettor after watching. ✌️👍

Great video of a great outboard, smooth and always with an easy starting

Thanks for your precise description. That helps alot. Great tutorial bro…

This was great, thank you!

Liked the vid. Are these not 3 hp and 70cc?

Perfect video 👌🏽 I've just picked up one of these engines, it's leaking fuel quite badly when the throttle is opened from the carb area. It's been sat dry for a while, but runs pretty sweet other than the leak 😬

How would the engine run, say if I were to forget to put that bung in over the pilot jet? 👀 would it stall with any more than a tickle on the throttle?

have you done a tutorial of replacing the impeller?

Ho un problema con questo motore non prende i giri è come se fosse strozzato e quindi manca di potenza ho pulito il carburatore ma è ancora uguale

Side filter intake ??? and gaskets when disassembling the fuel pump. Man, you know nothing about this carburetor do you.
