i have a 93 xlt sp 580, havin problems with gas fouled plugs. i just bought this 2 wks ago, it ran then, since then i have drained and cleaned the carbs, then it would fire up and ran perfect, but now, nothing. should i use a hotter plug? right now i am using ngk br9es, anything better? or is it that its just too warm right now? any help would be very much appriciated.

Did you clean the carbs before or after it "ran perfect"? If it ran fine 2 weeks ago i would not change the plug heat range. If all three plugs are gas fouled i would check for an improperly adjusted choke. If it is just one or two plugs maybe check for a stuck float in the carbs.

Lead, follow or get out of my flippin way

Usually because u probably didn't run it very fast or very long, plugs get a build up on them, which is why I rarely run my machine in summer. Change the plugs and give it a shot, don't run anything hotter than a br9es. You could try a BR9EYA though. They have a little V cut in the electrode, which supposedly keeps them from fouling. It's what I use.
