Now I do have a question the copy of the ipl I have is on my hard drive and bestbuy is still fixing my monitor so I have been stuck on the kids pc for a week and a half.. Sorry back to the ? The ipl shows a muffler gasket a shim and another gasket.The saw when I got it had none. I'm thinking the shim was a option and not all saw had it..So how to I know if mine needs it???Or do they all need it ???
That's the early style 064 muffler.....You shouldn't need the spacer and double gasket.
You'll know as soon as you try to bolt it on if the lower holes line up with the crankcase ok.
