Motor runs great, bough past year with very low hours. However, it does what sounds like a lean sneeze at idle only. Doesnt matter if warm or cold. Has done it since I’ve had it. Carbs cleaned, new fuel lines, fuel filter clean. I noticed that the top carb is slightly open at idle, meaning that it has to move slightly in order for the linkage to align. I’m thinking its a timing/sync issue, but I cant find a procedure specific to this motor. Have an island camping trip coming up this weekend that I’d like to be worry free at. Thanks!
