RTU Engine Compression Numbers

Anybody know what kind of compression results should be expected from this tractor? Minimum spec?

Thanks,

Jim

Depends on which head, how many cubes, cam grind etc.

My 228cid ZA motor with a 10A2648 head is right at 170psi at cranking speed. If you're still at 165cid, the common RE226C head, and stock cam I'd guess in the neighborhood of 90-110psi. Hopefully somebody who has pumped one will chime in later.
