Right now I'm stumped, my car has an intermittent misfire "pop pop pop" when idling and when being revved.
First I found the carburettor was pulling air where the float bowl meets the body, I then trued the surfaces with a file and sandpaper and made a paper gasket to ensure there is not even a whisper of air getting through, I've checked timing, coil, I've even borrowed a friend's electronic ignition from his distributor, there are no air leaks on the manifold, no blocked jets, I've tried gravity feeding the carburettor with some fresh fuel, tried raising the float height, replaced the distributor cap and rotor arm they were looking tired, same goes for spark plugs, and new HT leads (the cars been stood for years so needed those anyway) even checked in the dark for stray sparks and yet it STILL misfires.
I'm pulling my hair out, any ideas as to what it could be?
