That was a Mall model 7 that Larry attempted to kick start .No luck then he roped it over only to have it kick back on him and attempted to dislocate his shoulder .

Went to a small engine show in Marion, NY to help out a buddy here on CR (DeanOsaws). Cool stuff he had and got to run some of the stuff. The 2 man Disston was a 1946 DA-211 36 inch two man bar, 340cc 11HP twin. The saw was a **** cat and a blast to run, governed to 4K RPMs. We cut some off a dry piece of locust and the saw just chugged right through it. Learned that it was the bar-end guy's job to run the oiler which is a constant flow mechanical affair using a spring activated plunger.

Sorry no pics (I only have a 'dumb' phone) but a great experience, thanks Dean! I'll be back next year!

Well after talking to Dean for more info, that saw was a joint effort between Disston and Mercury Marine so it probably is some adaptation of a outboard engine. I understand that there was also a 12HP version.

Hey Tim, Thanks for coming over to the show... I was a great time!

The saw is a 1946 Henry Disston KB7-AY with 11 HP by Mercury... Not much info about displacement on these, but I found it listed as a 325cc engine and have verified that on another saw. Here is a pic:

Great saw. They're 245cc though. If that saw's a 1946 then it should be a KB6-AY. I have a 1947 Disston/Mercury KB-7AY 11hp saw. It's waiting for bench time and parts. Will be a runner again someday. I have 60" and 72" cut bars and a couple oiler/tailstocks for it. Got a mess of 3/4" chain too. Hopefully I can piece together at least one good loop for it.

Here is the big bow thing? Me and Nat and Al and John.

That could be one of a couple different models. If it's a 5-49 (my guess here) then it's 130cc/7.95ci. If it's a 7-55 then it's 161cc/9.82ci. Fuel tank's not tall enough for it to be a 99 (which is also 161cc). I have two 7-55's plus a buncha parts. Oughta be able to make one runner. Have a couple transmissions and bars for thes. Also have a 2-man post hole digger attachment for them.

There's not a nicer running two stroke than one of those Mercury Disstons. I just love the sound.

When I was a kid, I had a 1947 Evanrude 9.7 hp 4 cylinder outboard. It had a nice sound but wanted more oil than a quart in 5 gallons which is 20:1.

It wanted 16:1 which is a quart in 4 gals.
