Default Re: 39 deluxe not running right

If it backfires through the Carb. it is a sign one or more of the intake valves is not closed properly. Have you considered using some MMO in the motor oil, or the fuel. The Holley 94 Carb is very sensitive to backfire that can rupture the power valve. This will cause very hard re-starting due to flooding, excessive crank time before cold starts, rough idle, poor acceleration.
