- Sounds like a burnt exhaust valve to me (especially with the low compression).
- Even with bad rings, you will have some compression. I had an exhaust valve
- burn real bad on my '58; and one morning it just quit starting and backfired
- a lot. I didn't check to see if it was spitting fire.
-
- This should be fairly easy to fix with a pair of rebuilt heads. You may
- even be able to do it with the engine still in the car if you don't mind
- completely dimantling the alternator/fan/carbureator on top firststart by
- removing the alternator (and its stand) and then the fan shroud and
- carb/manifold.
