1.) So, what"s the number on the "lil round brass tag, clearly visible in your later pictures?
2.) WHAT engine is it, so far you have posted.... "AB", "ADH", and "AEH".
3.)Have you been to the manual download site I"ve linked below and downloaded the correct operator"s manual/parts list for the engine you have?
(UNFORTUNATELY it appears at least one page didn"t get scanned in the carb section of the ADH, AE and AEH manual,probably the one we need!)
