What he said! Torch tip cleaners are easier for me. They don't break. Just go 1 size at a time until you get a good clean run, and check the plug. There will be a point where it will sound good but most likely still be lean so be CAREFULL, and go 1 step over that. Put your pipe on, and open the jet 1 size/adjust the idle mix slightly on the rich side, and test run.
