use COLDER PLUGS. any dealer will have them. YOU RISK HOLING PISTON!!!

"Burning Out" Do you mean it is white or tan and burned or melted? If so I would agree with the first poster to answer and would add lean mixture. If you mean fouled, black, wet . . . then It might be too much fuel, too much oil in fuel, too little ignition voltage too cold a heat range plug, or too close of a gap.

ignition timing maybe retarded.....

r u using the right heat range plug.......try running a colder plug
