The Ford Barn - View Single Post - Holly 94 jet recommendation for a flathead running open exhaust?

F1 Flathead · 05-25-2010, 06:38 AM

Here's an update on this issue. I pulled the carb apart last night. It has .051 jets as predicted. The power-valve is the correct style in that it does not interfere with the carb body, but it is not labeled other than it is stamped "Keller". It appears to function properly. It is normally open and closes when I apply vacuum, although I can't tell exactly when it is closing. I think I'm back to square one since this valve appears to be doing it's job. I've got another carb I can throw on just as a test. Other than that, does anyone have any suggestions?
Thanks,
Dan
