My idle screw is set at one quarter turn, so Its been lean the whole time. Im assuming that if the thing ran, it should again. I just dont know why it would gradually require more fuel then quit altogether. How often do coils go bad on puchs? Im pretty sure that Im getting spark,but yesterday I pulled the carb off and ladled some gas in there without a single pop afterwards. I got a nice blue spark to the head when I tested it, but is it lighting the mixture?? Im frustrated.
