I am changing over to electronic ignition & 40,000V coil. I have a 12V system. Can anyone tell me what to gap the plugs at for best all-round performance? I have only seen one comment in another forum that said .045-.060 is best, but it was for a different tractor, and this sounds too generically automotive V8 to me. Thanks in advance for any advice.
Thank you everyone for the great advice. My plug wires aren't completely new, but they are still very good, premium wires and my plugs (.025 factory), cap and rotor are brand new. Cross-fire was one of the things that I thought about when I stated that I thought it sounds generically V8, because I sensed that this old systems engineering didn't take into account this possible upgrade. Thank you all again for the great advise. This is going to speed my tuning experiments tremendously.
