[QUOTE="ljtoy, post: 1078983, member: 17633"] [B]backfire(?) [/B]through the carb can be caused by: (1) intake valve just opening or possibly sticking while the next cylinder in the firing order is progressing through the cycle known as valve over-lap. {ie - check valve clearance - hot - possible weak valve springs} (2) [B]static crossfire[/B]. this occurs when one or more plug wires lose the ability to contain the high voltage going them to ground at the spark plug. this is how the current normally jumps that plug gap. shortest path to ground... (3) step up and install a [B]FACTORY OEM CAP AND ROTOR[/B]. I can put a TOY on the scope and [I]show you [/I]the difference between aftermarket and factory. (4) Ditto on weber carbs being flaky.. All kinds of strange stuff can happen. I had a 75 Chev backfire through the intake. Carb was Holley 4bbl and it blew off one of the primary butterflies. Talk about a "fast idle" !! [/QUOTE]
