    How many hours on the engine?
    Have you checked the plug wires/coil yet?
    Does it rev to high RPM's or does it start cutting out along the way?
    By caked up, do you mean with oil deposits or just black in color?
    Year, Make and Model?
    Any mods done to the quad?

    i was told it had a lil bit over 50hrs which a lil over 3 oil changes , got 140 psi compresion ,

    its a 2004 ozark 250 zuki

    no mods ,

    its like if i just held a lighter under a butter knife you can clean up the plug an it will give you a good 4 hrs ,

    after a lil bit you can hear it spiting (popin )at a higher rpm under load which is makeing me think its running rich

    i will come back with some pictures

    Have you checked to see how bright the spark is? Orange or blue? Remember remove the plug, ground it and crank, what color?
    What's the gap you're running on the plug?

    Have you check your air filter?

    I work on tons of quads that "keep fouling plugs" and most of the time i find a dirty air cleaner.

    Just a thought

    Verify that your needle and seat is sealing. should hold at least 6 lbs pressure. This will also cause rich fuel flow.
