The Ford Barn - View Single Post - Suggestions welcome- ‘46 runs rough when warmed up

Bruce_MO · 05-28-2026, 01:30 PM

I was thinking I’d go thru the carb again if the coil checks out. It doesn’t seem to be running rich per se; starts very easily hot or cold. Just a quick push of the starter button. I will choke it if it hasn’t run for several days, but I can push the choke mostly in after 8-10 seconds.

I can’t recall the specific power valve I installed in it 2 yrs ago, but I’m very familiar with all the issues and remedies for Holley 94 PV’s. I bought another 7.5 PV from Vintage Speed to put in it if/when I start chasing the problem as a carb issue.

Still not sure what carb/fuel issue is heat related… other than vapor lock!

Your comments are appreciated!
