72 C3 Cutting off problem
Hi, My 1972 C3 350 stock engine with 400 transmission is cutting off when kick down for few seconds then go normal. What could be the reason? Spark plugs replaced, air filter new and ignition timing ok.!!

Hi and welcome.
#1 Check that the 'secondary lockout' is OFF when the choke is fully open.
#2 Check that the spring in the secondary air valve is set correctly.
