Gear drive with that color scheme and no compression release (that I can see) indicates it is an 840 or 890. 840 is 99cc, 890 is 103cc so not a lot of difference there. The lack of an automatic oil pump could also mean 1-86 @ 99cc so still right in there.

I have a 48" bar on my 840 and it handles it well.

1/2" pitch chipper. I made up a new chain for that bar just for that project.

The 640 is not the super series engine and so would not have the shroud over the muffler.

Thanks for the 640 info Mark. I've had two and should have remembered that. I know they have the later convex starter cover.
