I dont know, I havent seen the one you have. the pulley is replaceable on the starter, unless the whole cover is broken. I had to take my dremel and cut the original bolt off and put a new hex head bolt throught to hold it together when I first did it, but it IS possible to do. I bought 2 of these pulleys when I got em, used one, kept the other for a spare.
Ok, I have the pulley now that I raided my stash of old parts.its even in the original bag, with instructions. part number 21963-00 according to the sticker on the bag.
Oldsaw, thanks for reply, havent been on computer lately to busy with outdoor projects. I am going by this morning to look at saw, and will get back to you tonight.
