    Is the oil only in the airbox? Is there oil at the bottom of the carb bell?

    DO NOT send any thing to whats his face (dirt-face/crasher) here on the board. What a scum bag. He screwed (stole) money from me and screwed me on my ME360 and Hondaline 300R engine rebuilds.

    Oil in the airbox could be from an over oiled air filter. And if the air filter is that oiled up, you could get excess oil in the carb too.

    there was too much oil in the airbox for it to be runoff from the filter. It was like 3/8ths full

    Over filling the engine will cause the engine to spit excess oil out of the crankcase vent tube. Clean it out, check fluid level and keep an eye on it. If it returns it could be something more serious such as a cracked piston skirt or broken sleeve causing blowby.
