My engine was supposedly rebuild when I bought it out of the car. It is perfectly clean inside and out, has new freeze plugs, gaskets,etc. I adjusted the valves cold and added a couple thousands clearance to be sure they wouldn't be too tight (FSM says to adjust when warm.) It doesn't look to have any new parts except maybe valves (hard to see). The pistons are not new nor is the cam.
Keeping in mind that the engine has NOT been started at all I did a compression test. The numbers run between 39 and 81 psi. After the test I got it running but seems too lean and would run best at full choke when warm so I'll be looking further into the carb. Vacuum gauge hooked to the base of the carb shows in the green and about 1500 rpm. No blue or black smoke. Checked for vacuum leaks with carb cleaner and found one, but didn't seem big enough to cause the lean condition. I'm hoping the rings were replaced and they just need to be run in? After I get it running better I'll check compression again and recheck the valves while warm. Will keep you posted.
