Slightly OT '53 six issue

I know those well. I had a couple of Falcons in the '60s that had the glass bowls. The Courier has an Offy 2 carb manifold with 2 metal bowl 1904s on it. I went in to the second carb today. Everything inside appears clean with the exception of a fine black gritty substance that sinks to bottom. The inline filter that is installed before the backup electric pump close to the tank is clear. I've only used the electric to prime the carb after the car has been sitting a while. Bad gas or a disintergating mechanical pump? The mystery continues.

It's a clifford, with a Holley 390. Not the best but, a lot better than the single barrel that it came with.

Excellent suggestion. I cleaned out the second carb. Started up and runs better. I ran your test with carb cleaner. No change when cold. Ran it a 1/2 hour it to fully warm up. I did the test again. The back manifold runner to the head has a slight leak. Tried tightening the two bolts on that runner. It made things a bit better. Its looking like a gasket replacement is in my future.

Great, I know you use this car alot and getting those bugs worked out is a must. This junky gasoline doesn't help, I had to go to bigger main jets in my 39. I runs better but MPG is way down. Good luck, Chuck S.

Well this saga continues. What I thought was a cure was not. I posted on the '54 & up section. http://www.fordbarn.com/forum/showthread.php?t=111288
