I've hade a high RPM miss for the last few races and I've changed everything in the fuel system (carb, fuel pump, etc.). Even when idling for a while, you can smell gas fumes and the plugs turn black.
Any ideas? Running stock HEI that came with the engine - I bought it new, no issues until now.
Might change distributer this week since I have a spare. Any other suggestions???
Thansk in advance, KB/UD
