Looking good Frank. Have you tried the Sharpie trick yet? (Coloring the teeth and chain chassis with a sharpie and then seeing what areas rub off).

It helps a lot. I used to do it on my long timber falling chains. I used to take the rivets down a little on the 8" bench grinder and then smooth them
out on the Jet belt sander.
I thought belt sanders were just for cutting cylinder bases?

I got caught up today, and it was sunny and beautiful, so I played with my Asian 440 Big Bore a little.

I gotta tell you I'm impressed with it. It is all Asian parts, except the piston, piston pin bearing and pull cord, and I did all the port work myself, and it is the first time I did any modifications to a carb (I opened up the venture).

I did not have any more rounds to cut, so I noodled some Red Oak and Red Maple. It started and idled well, accelerated well, and held speed very well in the cut. I'm sure it is not the best thing since sliced bread, but considering the jug is AM and has not been machined, and my porting tools consist of $6.99 Dremel impersonators from HF, and it has a modified AM carb … I'm pleased as punch with how it runs!

A medium size Ash tree blew down a few houses down from me and I got permission to cut it up (in the future) for my Daughter's firewood. I plan to give this saw it's first real workout converting the tree into firewood in the next week or so.
