Re: Finally built it but one problem
The screw on the left of the carb is NOT a mix screw on most models. It is just an idle set screw. Things to check:
Is the gas cap venting? Try with cap unscrewed.
Mess with the choke a bit.
Try moving the c-clip in the carb to the second from top position. You'll see it when you unscrew the top of the carb.
