My YAMAHA 4 stroke won't stay Running! How I fixed it 

I have the same engine. It had a flywheel, so I bought a starter, contactor and buttons for the motorcycle on Ali (about $100 all). The buttons are on the tiller. You also need a battery for this, but a small one, 40ah, is enough. Super cool

My generator was doing the same thing and stalling. I went on RU-vid, and found a video to change the carburetor. Fixed my problem and gave me that seems sense of satisfaction that you have from what you did. Nice job.

Another good way to make sure ALL the jets are clear and clean as they can be is to use a welding tip cleaner and compressed air. Good video, keep em coming.

Great job my friend. I also do the same as you. I may watch a video on the problem/ repair but it definitely makes me wonder if I'm doing it right. It's very expensive to have a mechanic do it so that's why I do it plus if something happens out on water I maybe able to fix it good enough to get back to dock then tear into it when I get home. Don't stop what you're doing cause it's great to learn. Take care, Steve

You are A stout young man I’m glad you got it fixed congratulations

My 9.9 Mercury would stop running after 10 mins .. found a small gas leak and changed plugs worked Keep sharing

You are a skillful fisherman

Hi Mate. I give you kudos not so much for cleaning the carb, but for doing what most people would not do. Ex. risking the engine going down the lake. lol

I'm so happy for you. I've got the 9.9 and will be cleaning the carb later today.

I also freek out trying to mount this on my dingy in choppy seas. Thought I was getting old and weak lol. Best wishes.

Dude thank you so much for this info. Been having exact same issues. Same 8hp Yamaha motor you have. Thanks again. Captain Dj Pope / Sailing Muse

Oh Man! I have a similar John boat and a 4 hp Yamaha. I’ve had to learn through trials and tribulations.. i’m about to do the exact same thing you did.. however, I wanted to watch some RU-vid videos first. Thanks for the inspiration I’m gonna give it a go.!! 🤞

G clamps and c clamps are good for many things like holding a bracket up for a bit

great effort

I really liked your video. I have the exact same problem with my 9.9 Yamaha 4-stroke and I know nothing about engines. However, I had this problem before and they rebuilt the carburetor and cleaned it. I'm thinking I don't need it rebuilt just cleaned. I wish you would have shown exactly how you cleaned it with that spray.

Man I bet that felt good 👏🏼👏🏼

Mr. Fix-it! 🎉

Well done, you fix things as i would? 👍 just one thing, if there was a chance its going for a swim, tie a rope to the front grab handle for quick recovery?

Thanks ,get rid of gray fuel line. The gray gas line will deteriorate clogging carb.. True story.

mine has same issue, I clean it, works great, if I don't run it for 6months guess what same issue, gotta be a better way

DIY FTW ! Now make a nice video of it running out on the water

I know a good lake we could put that motor to use on 😂

Somebody got some poon tang

yes i ripped up my finger pulling this joker too How about a better cord too its junk

reason they dont run properly is because yamaha under 20hp are still using carbs, whereas suzuki are EFI down to 9.9b, and also lighter, you should get suzuki instead mate, also make sure you wear the kill cord when you are driving :)

take the gas out after every use or make the same video next week
