G Compression Help

Fred from MO · Oct 1, 2012

I need some help from you G-guys. Im trying to help a buddy over the phone on his G (late 40s). He ran a compression test and got 45 psi in each cylinder. What is a G supposed to run? This is an all fuel tractor with most likly all fuel pistons. Thanks

I thought about all the all-fuel ones the I&T books says 75 lbs. Does he have the throttle wide open and the choke off ? to get max. air flow.

Good question Mike, I assume so but will check with him to make sure. Thanks for the 75 psi.

That's more than plenty. Especially since they're even. I have an A with 25 & 30#, it runs perfect, hand starts @ -25° in 2-3 cranks, & even with the petcocks open it idles perfect. Ignition & Carb are the key.
