I just finished break-in of my rebuilt engine and carbs. Fuel lines replaced two years ago. raves cleaned and re-done. New plugs installed. Everything is running great thus far except for a little stumble going from idle to any speed. This only happens after idling for a few minutes. The longer it idles, the worse the stumble. It will come slightly off idle before the stumble. If I hold the throttle at the stumble point sometimes it will clear on its own and go, sometimes it will not. However, If I either slightly let off the throttle or slightly press the throttle more, it will clear and take of. It has done this since I have had this ski brand new. It got worse through the period of tempo hose deterioration, but is better than it has ever been now since the carbs have been rebuilt and it doesn't do it every time anymore. Any ideas on what to check for this problem?
