This isn't a yz question but I'm sure you guys can still answer it. How does the temp of a spark plug affect the running of a 2smoke motor? I have EZ Go golf cart that I've lifted and put quad tires on and run around the desert in. I'm asking because it's a 250 2smoke and when I got it it didn't run so I rebuilt it put a plug in out of my old KX250. It has alwats run great but I've had the same plug in for a long time and I think it's time to replace it. I got the numbers for the plug that is supposed to be in it but they have a cold and a hot option. How will these 2 plugs affect the engine? I've never had a problem with it fouling plugs and would like to keep it that way as long as possible. Thanks, Khris ------------------ When in doubt, GAS IT!
