After buying and installing a G4 carby kit recently, I was having issues with the ignition pins. It seemed that no matter how I fiddled with those pins, I either had no spark or I had spark and the cut-off would not work. I wasn't prepared to stuff around with it any more and went to JayCar this morning and bought a marine-grade switch. It has a rubber boot over a stainless steel toggle, and comes with the wires attached so that the ignition pins plug straight into the connectors. This switch needs a 13mm hole which is easy with a step drill.
Honestly, it's not worth stuffing around with those stupid pins in the G4 carby. Sooner or later they play up.
