Re: Too much fuel, not enough air.
Float needle dirty?
If gas comes out the air cleaner, clean the needle and seat and get a inline fuel filter to prevent trash from getting into it.
Every single kit I've built had paint chips and assorted trash in the tank, and even after cleaning, paint still chips off from around the gas cap opening for a long time.
A fuel filter is cheap insurance.
If more is better, then too much is just enough.
If you can't afford it, build it yourself.
