Bad news, only 1 cylinder had adequate Compression! It was supposed to have been rebuilt by a machine shop in Va. you recall I’ve not been able to get the rings seated, been using oil 🤪🥸.
# 3 had 90 lbs, all others were 35 or more after revving up the motor.
I don’t suppose there are any other tests I can do?
