I just put a new head on a Kaw FH721d-as04. I can't get the thing to pull a load. I adjusted the governor per the manual, but it would not rev up. When I push the governor/throttle linkage forward the engine revs. I moved the governor shaft to allow it to run faster. It will with no load...
For some reason, my horizontal shaft kaw bends push rods. The first time the coil pack failed, engine backfired and bent rods. Second time I backed into the creek, bent push rods. Any idea why? I'm able to put them back and it runs great.
This last time I took the crank case cover off...
