Re: pleeeez help!
Remove the bowl from the carb. The main jet is screwed into the bottom of the carb body, through the plastic float. It's actually in two pieces - a small jet into a longer emulsion tube; it's the emulsion tube that can get loose from where it screws into the carb body. Make sure it's all snug. Don't lose any bits, paying close attention to the pin that holds the metal float tang on, and the needle valve that that tang operates.
