So I have a generator that has a Walbro LMT carb on it but it only runs on full choke. I pulled the carb off 3 times so far tonight and used 2 cans of carb cleaner with no luck.. Am I missing something here? I pulled the main jet emulsion tube out and made sure that all the little holes on the sides are cleaned, shot cleaner down every port I saw but nothing. Is there a port on these carb that is harder to find?
