ya my cousin just bought a 2001 mxzx 440 from the dealer and he is going through plugs like crazy. He is mixing the gas/oil at 33 to 1 like is says. could have the person rejeted it so he is running it to rich. what are your thoughts?

33:1 is for race gas with the High Compression domes.

Assuming he has the low compression domes, he should run 93 octane and a 40:1 ratio . 2 of my buddys had 440X's 1 '01 and 1 '02, and had the same problem as your cousin does 'til they talked to someone and were told to run 40:1. Never had a fouled plug after that.

A clutch kit in that sled will make it rock even more. :div20:
