quadmaster 500 backfire issue!
Have you checked to see if your fuel petcock is bad..? When mine went bad on my 300 KQ it caused backfires, no power, hesitation, no idling, etc. May or may not be the issue, but it's worth checking it to rule it out as a possible cause. To check it, (With Atv Not Running). Pull the vacuum line off at the fuel petcock, (Smaller Line). If the line is wet, or fuel comes out that line or port where you removed that line, then your fuel petcock is bad and needs to be replaced. Again, may or may not be the issue. But never hurts to check it.
