I have both rim style sprockets and spur type. I personally like the rim style a little better. It usually a little more expensive, but after that all you have to replace is the rim itself. I have good luck with both. With the rim style you can change the ratio also, like a "7 pin" or "8 pin" rim etc. Most of these saws are best with the standard 7.
As far as getting the flywheel off goes. I usually will take the nut & washer off. Spray a shot of PB Blaster or some such stuff on the theaded end of the crank. I will "tap" I repeat, "tap" the flywheel with a hammer on the solid side of the flywheel, up at about the 1:00 o-clock position. If that doesn't do it, I will put a socket big enough to go over the end of the threaded crank end, but that will sit flush on the center of the flywheel. And give the socket a rap or two. Will usually pop right of.
Just don't hit the fins on the flywheel or the cyl. for that matter. Can easily break fins when trying to pry with a screw driver. By the way. You almost have to remove the flywheel to remove the fuel tank.
Gregg,
That's the cleanest looking used saw I've ever seen. I feel like my cleaning job sucks now.
I'll have to mess with the flywheel tomorrow, I'm done for the day. That thing just kicked my ass. Now I have to figure out how to put tension back onto the pull rope. This service manual assumes the reader isn't totally ignorant. I need to search You Tube for some visual aides.
