Re: Gas leaking out the air intake
Ditto on both counts. The float valve isn't shutting off the flow of fuel from the tank when the bowl is full. Either the float is defective or there is dirt in the needle and seat of the float valve. I suspect dirt in the valve seat.
The kit fuel tanks should be cleaned and flushed prior to installation. They usually always contain rust and dirt. An in-line fuel filer is highly recommended but they can clog if the tank isn't cleaned.
