it for 10 mins it never fires, buy the plug is barely wet. comp is 120 on all 3 cyl. THe dealer just rebuilt the carbs. I imagine they checked the reed valves."

"Tony,

It sounds like there is a problem in the lower carb. Maybe they everlooked something. If a reed valve is broken you should notice some pressure at the throttle bore. Hold a piece of thin paper over the bore and crank the engine. If you see the paper being pushed out, you probably have a broken reed.
