Having problems getting a flathead in a 41 fordor to run right. Did a compression test this AM. All but #2 come in at 90 lbs or better. #2 comes in at a paltry 30 lbs. Added some motor oil, but no change. The test was done cold as we cannot get the thing started right now.

Car sat overwinter each of the last couple of years after purring and running like a kitten 2 years ago. Had similar rough running last two years although this year its particularly bad.

We have poured in some MMO and are going to let it sit till tomorrow. I'm thinking a valve problem, hopefully only stuck open, and not rings. Any words of wisdom?

Would one cylinder with low compression cause the thing to basically run like a piece of.... you know what I mean.?

Any comments would be appreciated.
