that stihl 026 i found a little while ago has a spur sprocket/clutch drum on it,its .325 pitch,itll be the factory one and looks a bit worn,i prefer the wobble rim types anyway so bought a non genuine kit from a reputable seller ive bought a ton of chainsaw stuff from over the years,it got here promptly and once set up it didnt spin right by hand,it bound up straight away.(i always spin new chains etc before the cover goes back on!).seems to be incorrect pitch but is marked/stamped correctly,its a 7 tooth,i have a spare 8 tooth for another saw to compare with,some things not right with the one supplied,i contacted the seller by phone,explained i had photos to show but were happy to send me another rim sprocket,i said check it on some chain first make sure itll fully wrap without riding up n over!
