    but you didn't say about the advancer - if the breaker cam slipped off the advancer and was put back on 180° off (and it can be) it will do that

    I figured it out, the battery was not strong enough to keep cranking the engine over and it disengaged from the engine so the engine just pooped and popped until I ran jumper cables from my truck. After about 20 seconds of cranking the replacement motor fired up, smooth and quiet. The way the engine reacted to the low battery had me fooled, now it has a new lease on life

    I think most of the previous posters mmissed your finding Compression: "140 lbs compression both sides"

    A healthy 350 has 180-185 PSI on both side with less than 5% variation.

    The FSM spec's below 150 PSI requires a rebuild

    the poor compression readings were due to my ignorance using the gauge, I figured out the problem and the motor runs great
