Haven’t been in the basement much lately, but wanted to keep this post alive….I did go back and actually check compression, 75PSI on both cylinders….This reading seems “OK” considering the engine is on a stand facing the wall and I could not give the rewind much of a yanking.
So, next, I will try a different carburetor when I get back to this thing. I think I left the original reed plate with this replacement powerhead, just swapped the outer intake cover from my “rebuild”, so I don’t feel the reeds are an issue.
The only other idea that popped into my cobb web is that I did have the gearcase apart and replaced the driveshaft. Perhaps the gearcase is binding at high speed, or the impeller is an ill fit, although I only use the OEM pieces. This gearcase does not have the driveshaft shock absorber, so that is not the issue here….
It’s gotta be something silly and basic that I have overlooked or made a foolish assumption about….
