With a barrel valve that has a part throttle bypass, you can run it clean at any rpm . ....you can get one from Kinsler.......If you don't want to change the barrel valve,then use the electric bypass, tied in with the timer......without a bypass,you need to get as low as possible on the stop rpm,while going out farther than a carbureted car before going on the stop. .....Tom
