Relist: Other.
Not his fault, I dropped the ball by mistake. but since then I have not been able to have any marine mechanic ( or this gentleman respond to my question) Again the fault is my own, but I (perhaps wrongly so) infer that I am being rated as well by experts and have a blemish or 2 for leaving him or others hanging or possibly not tipping well enough?? Net net no boat mechanic will respond to me when my history and experience is that i typically get an answer with in 5-20 minutes on average

Hello Greg, welcome back.
I was at work when you replied.
How is the spark on the engine at this RPM? Using a timing light you can check it.
How do the spark plugs look on the engine? Is one whiter than the others?
If you were to squeeze the primer bulb with the engine at this RPM would it run better?
