I Recently bought a 1954 Savoy Club Coupe and for the most part it runs great, except when getting to cruising speeds.
When I first got the car and tried to drive it down the road, as I got close to 35mph, the car started surging/chugging and wouldn't accurate any further. After looking around I found a kink in the fuel line and suspected it may be causing a fuel starvation problem at higher RPM. I fixed that and can now get to 45mph before the same thing happens. The carb appears to have a slight leak so I've ordered a rebuild kit for it, and while the filter looks fine, I'm going to replace it as well.
Is there anything else I should be looking into? To me it seems like a fueling issue, but I know I don't know everything.
I live in the county where the speed limit is 90kph, so I need this car to do 50-55mph, which my 1950 Ford was capable of, so I assume this Plymouth should be.
Eventually the plan is to swap the rear for an Exploder rear end with taller gear and maybe a 5 speed transmission, but until then I'd like to make the OE parts as usable as possible.
