+Crazy Gaming Mike sounds like the carb needs to be redone. A tiny amount of carb spitting (gas) is normal. If the is gas spilling out the carb mouth, I know of only three reasons why this could happen. 1 - Welch plugs not sealing correctly (unlikely), 2 - Nozzle check valve is bad usually does not go bad from one day to the next), 3 - Needle and seat is bad ... or dirt is hindering the good operation of the needle and seat. My bet is on number 3. I hope this helps you. If you have no experience with these carbs, maybe find someone who does. They can be finicky at times.
