I have a '74 "B" engine that sputters on take off as I let the clutch out.
Once the car gets moving, there is no more sputter. It sputters like you
would expect a car to sputter with a cold engine on a cold day. Problem is
that it sputters at normal running temp on a warm day. If I rev up the
engine and take off slowly, no sputter. As I move through the gears and get
up to speed, the car runs great. The sputtering seems to have started a
couple of months ago and has gradually gotten worse. The engine has a Crane
electronic ignition kit in the original distributor, a Crane fast street cam
and a Weber down draft carb. I've just turned over 9000 miles since I
rebuilt the engine. Any suggestions?
