Just picked up a used 250sx. Very good price. Dumped old gas and oil refilled all, gas at 32/1. Rode at Glamis last weekend and fouled a plug every hour. Did visual of cylinder and piston through exhuast port and looks good so I dont think its rings. Oil level didnt drop so I doupt its crank bearing letting oil through. It was spitting oil from exaust bad. I dont know what jetting is but iddle screw is cranked all the way in and it still has hard time idleing. I'm new @ 2strokes so any help or ideas would be great.

I thought about the jetting but would it be showing that much oil from pipe with wrong jetting? Maybe I,ll pull carb and see whats in there. It was originaly from Ohio so who knows. Thanks
