ok, is the backfire through the exhaust or inlet manifold? if its through the exhaust it means ur mixture is to rich, causing unburnt fuel to ignite in exhuast, if through inlet it is a lean backfire, either way if carby in good condition it sounds like mixture screw, to adjust, start car and get to operating temp, wind mixture screw in till car almost stalls then back out 1 and a quarter turns, that's a static point to go from. good luck
a c-4 will work
