    Probally in the fuel system for sure. Check filter first then it is on to the carbs.

    Low side jet of the carb is stopped up. The jets in 4-strokes have small jets. And stop up easy. Get the carb cleaned. Then keep Staybill in the gas. You may get lucky and run Seafoam through a tank of gas. If your lucky it may clean it up.

    I second the motion on SeaFoam, it's good stuff.

    I second the cleaning of the carbs. I would take the carb completly apart soak them then put them back together to make sure you get all the junk cleaned out.

    hi joe,you probably just need to take the carb apart and just soak it in carb cleaner for a day,wash it off with water blow it out with compressed air put it back together.should fix your problem.you may have to get a kit but don't be afraid of the job its pretty simple,idle circuit is probably stopped up from setting.hope this helps.

    You have to take the idle jet out to clean it. Just taking the carb off and the bowl. Will not do it, I did the same thing to a 25 yamaha 4 stroke I had. Be careful of any carb cleaner. As it does not do well with rubber or plastic parts.
    Those parts need to be removed before dipping in cleaner.

    You may need to use a bit of compressed air, as the solvent itself may not be enough. Yahmaha makes a good product called "Ring-ER-Free", you can use it to clean with & put into the fuel system.

    Completely dissemble that thing and take the rubber and plastic thingys off and soak it in berry man carb cleaner all nigh and then blow it out with compressed air. Use a rebuild kit and rebuild it. This is why I drain my carbs in the winter.

    I had exactly the same problem in a Johnson 15 horse,, I ordered a carb kit, and when I got it, removed and disassembled the carb completely,, in any suspicious areas, I ran a piece of mono through it,, came up with some trash in some of the ports and orifices, cleaned it up, blew it out, reassembled and ,,,Look at that thing GO!!!

    I'm no good at cleaning carbs, i let the pros take care of that, but once you get it clean:

    Put a fuel water separator/ fuel filter on the fuel line
    Keep stabil or seafoam in the tank at all times

    This is the advice of the yamaha dealer where i bought my 2 stroke. I heard them talking to a few people buying 4 strokes. As has already been mentioned, the dealer said that the 4 strokes become easily clogged with trash and water in the fuel.
