Have been working on my first carb rebuild, TSX 241B, when I can and I think I am down to one problem now that I am not sure what to do about it. The throttle shaft bushing that was on my carb before rebuilding looks like it was a couple of brass bushing, one inside the other (actually looks like they split one and wrapped it around itthe other), with rubber gaskets(?) below the bushings, i.e. between the bushings and carb body. I ordered a new throttle shaft bushing but as I suspected, the hole where the bushing goes into the carb body is a little too large, there is a little extra space around the bushing. Any ideas on what to use to fill the space to keep the bushing from turning in the carb body. It's not much space there but I am concerned about the bushing turning and it not sealing since it is not set in there tight.
