With the 1st compression test reading zero in #2, and then doing a valve adjustment and repeating the compression test and now getting 15lbs in #2, is it safe to assume that this is a valve problem and not rings?
More history, the motor has less than 10K miles on it. Was a good running motor. When it was redone a few years ago I bought a short block from BP and had the head rebuilt locally. Have always run unleaded gas, was told the head has hardened seats.
It started running rough several weeks back. I'd re-time the motor and it would run good for a few days or a week and then need re-timing. I've had dizzy issues in the past so I bought a new dizzy. Plopped that in, checked the gap, timed it by ear and drove it about 15 miles across town, freeway and city streets, ran good. Jumped in it to head to a friend's house and it died on the way. Have not been able to get it to run other than momentarily/badly since.
Over the last few weeks I've replaced the coil, high tension wires, spark plugs, distributor. I've rebuilt the Rochester carb, second time in the last 2 years. I've tried running the truck with a Zenith off scott's ambulance which runs with that carb. I'm hoping now that it's a valve issue and not rings.
