A buddy of mine that has a 1995 Force 2 stroke (premix) 40 horsepower motor runs good idling but has a very small miss at WOT just enough to notice, and it only does it every couple of minutes...its getting enough fuel, we went for a boat ride in the river and at WOT i tried to spray some pre mixed fuel in front of the carb and it lowered rpms, but then picked back up....i even took the carb apart before we went it was spotless on the inside, also did a compression check just for the heck of it, they were both 145 psi
he took the boat to a mechanic last week and the mechanic did a water pump kit,changed the spark plugs ( he put NGK in it) and an idling timing adjustment...before it went to the mechanic it ran fine on the top end but wouldnt idle quite right, but now its the opposite...do you have any suggestions ?? the mechanic is stumped so it wont be going back to him thanks in advance
