I have an old 31cc Ryobi weed eater motor I am salvaging for another project. I am trying to to get the centrifugal clutch off. The outer shell came off with a 15 Torcs driver. On looking at the internal portion (that mounted on the shaft) I am trying to determine if it is pressed on or treaded. There is no keyway and there maybe threads. I can't tell. Could one of you wise souls tell me if I need to put a puller on it or figure out how lock the crank so I can twist it off.
TIA
