I have a 1992 25HP two cylinder 2 cycle Tracker by Mercury outboard in generally excellent condition. It has been stored for 9 months while I was recuperating from surgery. It now has a random miss at all rpm ranges. At idle it lopes like it has a hot cam in it.
Compression is 135-140 on both cylinders. Spark appears strong on both cylinders. New plugs had no effect. I hesitate to think it is a fuel problem because the misfire occurs at all rpm ranges. Fuel is fresh, never any ethanol, and the filter looks like brand new.
I would like to try diagnosing the problem myself before resorting to take it to a shop (there aren't any locally), and would appreciate any thoughts from those who have experienced this issue.
Thanks!
