I've been chasing a problem with my '51 stumbling and stalling for the last several weeks. When I've been able to look at it, I just couldn't find the problem. I can smell a strong odor of gasoline around it and the exhaust/intake manifold gasket was soaked with gas so I thought it was the carburetor. Turns out it was a loose bolt for the two points wires in the distributor!! I swear I checked it before, but after tightening the bolts, it runs great again! Now it's off to some car shows in the area!!
