Good morning, my name is ***** ***** am I speaking with?

This can be a few things so lets start with an easy test first. Remove the spark arrester. start it up. Run it until it misses .

1. Is the choke opening up?

2. If yes, look down the throat of the carb, do you see fuel dripping or pooling as it is missing, or stalls out?
