I had to play with mine when I first got it. The motor was rebuilt at some point, when some one changed the intake to a four barrel from a two barrel. They added a cam durning
the rebuild, purchased a E carb to go on it with no adjusting of any kind. The car was running way to rich, pulled the carb, changed out the jets, rods and springs to a smaller set.
The car runs a whole lot better, but I think I can still get it a little better just need to find the time.
