99 Mag.500 backfiring thru filter with RPM
1999 Magnum 500 in remote Alaska Bush. Backfiring through the air filter with any amount of RPM. Won't run past an idle 
Changed plug, drained carb, changed fuel, adusted thumb screw bottom of carb, checked air supply through filter (filter bottom wet with gas) tightened rubber hose from carb to cylinder, checked fuel filters.
Now have removed carb. Flew it back to the lodge, cleaning it. If that doesn't work:
Suspect: Timing changed somehow, Coil or CDI
Any Suggestions
Wildman
