I was wondering if anyone knows the spec compression for a 656 gas. I'm still waiting on my manual to come in the mail and was just curious. I did a compression test and the cylinders ranged from 105 to 120 psi. Thank you.

If it were mine I would not be concerned. Squirt some oil in each cyl and see if comp.increases.

I-T manual says 155PSI at sea-level with mag pulse ignition but that is also for an engine that has little to no wear on it so your numbers while not perfect nt bad either for an old tractor

I agree. I was just wondering what spec compression was. Thank-you!
