Hi all
I recently picked up a 74 2.0. This car has not run in 20 years. I pulled the gas tank and fuel pump which was a mess. I changed the oil and I pulled the plugs. The compression is even on all 4 at 70 lbs. I know this is quite low. Is this to be expected? Should I try to get it started before doing another compression test or should I just resign myself that this motor must be rebuilt. I does have 88K on it. Thanks Mark |

depending on how long it's been sitting, it might need some miles to let the rings re-seat to put up a decent compression #...
Sounds like a combination of a weak battery and a closed throttle caused this one though. Re-check w/ a fresh battery and the throttle WFO BJH |
