[QUOTE=Ed_Moorman;504762]The carb for the ASP .91 should be the same one as for the 1.08. For either of these carbs and for the OS, you need the split sleeve the early STs came with to reduce the hole in the crankcase to the size of the carb neck. Great Planes used to carry them. In a pinch you could use aluminum tape.
anyone happen to have a picture of one of these split sleeves? I just bought one of these s3000s and the carb measures 15mm but the hole in the case is 17mm. Needless to say the just flops out of the hole. I can’t find any info on this missing part anywhere. Can’t find a parts diagram or a part number. Please help.
