I had problems with my mantis last year (I bought it early in the year used) running. I knew that the PO didnt take that great of care with it so I tore down the carb and rebuilt it. Needed it cause it was all gummed up inside. Flushed the tank clean, put new fuel line and and strainer on it, plus a new plug. But now I cant seem to get it started. I am wondering if the idle screws are not set right. Does anyone know where they should be set at?
