Hope somebody can help!Just rebuilt a 1972 chevy 350 with a new
crankshaft,edelbrock torquer plus cam,torker manifold,holley carb,
summit 1.6 ratio rocker arms,HEI distributor.This motor is in a 1979
nova and ran well before.Now when trying to start it backfires
through the carb something terrible.Have tried readjusting the
valves,and thetiming looks good for starting(checked with timing light).
Any ideas?I'm dying over here.
