Thank you, amuller.  The synchronization process that I have tried is in the attachment.  Does it seem correct to you?

 

What baffels me the most is the fact that loosening the two bolts for the throttle cam does not let it move at all.

Kind of hard to follow with no pictures.  I’m wondering if this engine uses the “economizer linkage”?  If so, I was guessing that it might not be set right causing a lack of power due to only partial opening of the carburetor butterfly at WOT.

Charles:  feel free to post a picture of the left side of the powerhead with the engine cover off, then we can see if it has this linkage…  D
