Peter,
Check your compression again. Be the engine is warm and the throttles are
wide open (remove you coil wire).
Squirt a bit of oil in the cylinders and repeat the test. If the
compresssion jumps up it is most likely the rings.
What I would suspect on a newly rebuilt engine:
Incorrect ring end gap
Incorrect break in procedure
Used a synthetic instead of mineral oil for break in
Possibly the rings were installed wrong side up?
This can happen on a Chevrolet. I'm not familiar with the
ring comfiguration on a TR-4.
Thats all I can think of for now. Let us know what you find.
Regards,
Chad Jester
