Would 45-50lbs be good compression for this machine??
I goofed and posted in another forum area and then found this quad area..
LMK please!!!

No that is very low compression. I don't have any specs on it but I would say it would need 120 to run good. I know for a fact that a 250R will not fire with 70 psi compression.
