59ab compression numbers

After lots of troubleshooting i finally found the problem. Shutoff valve on the bottom of the tank was full of crap. Bouncing are just right would cause it to plug. Fuel pressure gauge would have made it quicker to find.

Thanks for posting this. Good for all of us to hear how a mysterious problem got resolved.

Just an fyi. These darned old flatheads run pretty well even with just 65 pounds compression. !951 ford in mine was smoking till I put in a pcv valve. I would prefer more compression but away it goes down the road

Yeah, she’s running well now that I’ve fixed the fuel problem. I dare say it has more power now than when I first put it together. Wonder if it’s always been plugged a little and just continued to get worse.
