My motor is coughing/sneezing when at idle, occasionally stalling. Does anyone have a solution for this? I have heard it may be a running lean, but not sure how to adjust that.
Thanks,
Jeff

Clean the carbs and fuel system and adjust as the Service manual calls for in specs.

Jeff I have the exact same engine. I went and bought a can of mercury power tune. I followed the instructions to the letter. Made a huge difference to the engine. Your plugs are fouled and the engine needs a clean. FOLLOW THE INSTRUCTIONS TO THE LETTER!!!!! I cant stress this enough. It made a huge difference to my engine. You may need to idle the engine UP once you have completed the instructions. But It will be a different engine.Comment

I have owned yamahas for 25 plus yrs, the Achilles heel of the two strokes is the carbs, when was the last time you cleaned the carbs? I would strongly suggest you have the carbs cleaned, a lean situation will burn a piston in short order.Comment
