I have 3 marvel carburators and just want some history or any type of info on them. I have heard they were made by sears, and i also heard you can get 10 more mph with them. Any info would be great. If you run a marvel let me know how you like them.
i have a 29 steel back and it runs great but once i hit 45-50 mph the car start to sputter basically it jerks like it want to go but cant. Whats the problem?
