In addition to that at the local antique tractor pulls in spring it couldn't move the sled more then 7' without almost stalling from lack of power. It was the only tractor there that had that issue, it was only in the 3,000 lbs class since it has no ballast or weights. [Reply]   [No Email]

Iirc those 22"s had a very fast road gear ? Wouldn"t be the first time an engine mysteriously low on power due to a worn cam. A re- grind is the answer there as all used cams are worn to some degree.

I haven't checked the valves yet but I did do a comp test, all the cyl's were around 30-35psi at idle and 80-90 psi at 75% throttle not sure if that's good or not so good though. [Reply]  [No Email]
