OK i just rebiuld my LS motor, New piston,rings all new seals and gaskets. Well i put the motor in over the weekend and it wouldn't start. I finally got it to start but i have to keep pumping the gas to keep it running. If i let the gas go it stalls and if i hold the gas steady it stalls. I checked the compression and it was 120 psi in all 4. Normal is 180 - 210. but i think this is becasue the rings haven't seated yet. Can anyone give me ideas on what to check. Now i'm not sure but i might have put the head gasket on upside down. Could this cause my proble if it is on upside down? Please give me and ideas you have so i can start checking ASAP
