Prying is definately not the way, not going to do that, dont want to damage anything! I assume it needs a special tool?

There should be a couple of holes there on the clutch ¬ the threaded bosses that are used to hold ther clutch cover plate on.I use two drift pins & then put about an 18 in,piece of flat stock in between the drift pins & turn the clutch off that way.It's a little different than the Macs,but generally the same idea.There's also a clutch removal tool on Ebay for $22,but this might not work on the 750.

Awesome, really appreciate the info! I think I am gonna really enjoy this forum! Bar has been ordered, and now I gotta find a 3/8 sprocket! Since you have a 7 spline drum, the easiest way would be to put on a new rim in 3/8. Personally I would use a 3/8 8 tooth rim.

Started breaking down and cleaning the saw up today, it is filthy! Looking at the carb, it is a Walbro WB 9, and I cant find a rebuild kit for it on rbay or anywhere else. Is there another kit that will work for it?

You are probably going to want to replace the carburetor boot also, it goes between the engine and carburetor.

Hey all, just wanted to say thank you again for all the information and assistance. I wound up getting a 750 parts saw that came with a 36" bar and chain that was 404 and 063 and fit the one I am working on currently. I will still be on the hunt for a 3/8 rim sprocket. The parts saw that I bought had the spur style. Hopefully this weekend I will be able to get the 750 put back together to post my first picture on the forum!

I was taking a look at this tool and was wondering if anyone with one of those saw measure the sprocket holes diameter and space between them? I contacted the seller about a week ago and have still heard nothing back.

That looks easy enough to make.I'd just need a couple of pieces of flat stock & someone who works in a machine shop to mill out a slot in one of the pieces (or find a piece of flat stock that's already milled).Drill a couple holes & that's it. Ed

I appreciate it, finally found some taper pins that would work and made a home made tool but may still get the proper tool in the future! I was able to at long last remove the drum and sprocket but they didn't tell me all that much in the way of what to order or look for. The drum had no writing at all and the rim sprocket was a powermate 404-7. Rim Sprocket home2 by Justin Jacobs, on Flickr Drum home1 by Justin Jacobs, on Flickr

404-7 means it is .404 pitch and 7 teeth. Standard nomenclature not dependent on the brand.

Two pieces of flat stock bolted together then each bent a little to line up the ends would work. They can be bolted at the end to make the arms and thus the angles of the bends as small as possible. The bends should be near the bolt.
