Surging sounds electrical. If you think its the lack of a foot rest. Use the hand throttle. How does it run through the gears full throttle? Whats the history on your coil and distributor?

Edit. sorry Chrisabes. I see now you had the same idea two posts up. I just put a flame thrower pertronix coil on my car and I was surprised how it smoothed out my idle and cold running.

Another thing i thought of. The worst my car has ever ran. Back firing like an old movie scene. I had a loose generator connection when the battry ground cable lost contact. Moral of that story check all your connections.
