This is a Mall model 7 two man chain saw that has a 36 inch cut and a good 3/4 pitch chain on it. I manage to get it running
(see movie) but I wouldn't say it runs good it does not idle consistently, but once it is pulling it seams to have a lot of power.
I did not spend a lot of time on this nor do I want to. I replaced the cork float and put a new plug in it and that is as far as I got.
I just have too many other projects and this is taking up to much space so it has to go. The handle bar needs some repair also.

For those of you who don't know this was introduced  in 1946 and is a single cylinder 12.19 cu. in.

As you can see below the chain looks to have a lot of life left in it I sharpened it and I would sat that was probably the first time.
