The A-65 with the Stromberg carb had some problems with the engine quiting on final. Once I put a Marvel carb on and tossed the Strombrg, it never happened again. A little less drastic is to send your Stromberg in to Don Swords and have him overhaul it.If the carb is a Stromberg and it is many years old, it should be overhauled anyway. There were several different carb fuel float parts which were blessed and then unblessed. The pointed part which shut off the fuel when the bowl was full went from something I don't remember, to stainless steel, to delrin. Give Don a call and let him make you smart before you spend any money.Google Don's Dream Machines...Sorry about the formatting. This site is not IPAD friendly.Pete
