Although the car is old, the engine is a brand new Jasper 350 with an Edelbrock 600 cfm carb and a new Mallory ignition. The 93,000 miles isn't significant because the car is fully restored.
When the car is cold, it backfires at the carb. When the car warms up to about 170 degrees, the backfiring stops but the engine hesitates a bit and doesn't perform well.
I have tried everything with the choke and mixture screws but I cannot get this thing to stop coled backfiring.
Besides the carb, what else can cause this. I have checked for vacuum leaks and find none.
have the same problem?
