    fuel in box solved,floatbowl was sticking. Next airbox crud question, is there generally a coating of oil in the airbox that seeps out the bottom?

    That sounds like crankcase breather/PCV valve in the rocker box cover, how many miles did you put on it with it flooding? May have washed/wore the rings enuff to get a little excessive blowby.

    I put 700 miles on it in the last 2 months. The odd thing about the gas leak it was only at highway speeds 70+ The oil issue only started a couple weeks ago.

    Oil issue is because at stock the PCV valve is vented into the airbox. Re-route it to the ground and let it drip there, or plug it and put a small air filter at the tee and use a cable tie to secure it somewhere. Not an issue either way, comes from the factory like this for emissions control. I think its safer to re-route it though. If you need pics to see what I am talking about, let me know.

    Rings will be fine as on the blast the fuel pours out the inlet rather than into the cylinder.
