I am beginning to believe this big *** prop is my trouble. The 15x17 i found for $40 was sold before i could call. Based on what i have read through here i am leaning towards a 14.5x17 prop. Right now i am swinging a 15.5x14 and also have a 15.5x15 aluminum (spare) that does even worse.
I put my throttle wide open, and yes, all carbs are wide open. So my issue is not there i believe. I was able to run it on the hose and use the rest of my sea foam out of my 6 gallon tank that i couldn't use when running.
The previous owners have put some money into this motor. She cranks within two seconds now.
Also what should my compression be?
