RE: need throttle stop screw for team infinity .18 slide carb.
Have you tried contacting Infinity directly? I think Tower Hobby carries some carb parts, but Im not sure about Infinity.. Possibly you could match one up from a differnt brand, but something as precise (and small) as a carb stop screw, your probably not gonna want to mix-match.. I think your best bet may be to try and run down (google search) a phone # for Infinity, and see if you can get them to send you one.. Good luck!!
