YES, I did it
But you have to be very finesse about it or you'll mess up your carb.
Okay! Let's me tell you the long story. As I was playing aroung with the ait mixture screw to get rid off the backfire problem, I did pay attention to the slowly deteriating head on the screw. So a lots of fine brass got in between the threads on the screw and the carb. Now the screw is getting harder and harder to turn back out. In other word, it's stuck for good in there. The only otion I have is to buy the SPIRAL FLUTE SCREW EXTRACTORS size #1, and a new air mixture screw from
www.ronayers.com/ . The tool you either go to auto part store or do some search on the net. You will need a small center punch or something that are small and have a pointy head to mark the dead center of the screw. Then use a 5/64" drill bit to make a pilot hole for the extracting tool to catch on. REMEMBER BE VERY GENTLE AND SLOW WHEN DRILING THE PILOT HOLE and make sure that drill bit is going straight in according with the carb's air mixture hole. Sorry I don't have the will take picture or the know-how to post it on the web. If you really really want to see it then IM me.
