Found a set of rings. Thanks to Mark Loraine for posting some part numbers. The big saw motors would be fun to play with, but I am sitting on too many of the early saw parts. After running down D44/55 donors for Mc 10 parts then the 1/70/80 for the rest, I cant just toss these leftovers away. Since ...

I could use standard size rirngs, Basically something with less than the 1/4" end gap like these have. Right now I have a bunch of 2" 0.024" thin rings, some thick rings that measure 0.057" that almost work, but the side clearance is too excessive. The 1/16" rings I have are either 1.875" or 2.125" ...

Thanks I will keep an eye out for those part numbers.

These particular saws have governors, which I do want to keep in use. So a larger carb would have limited benefits. Opening the venturi from 11/16 to 3/4 would improve a little. But the intake tract is so restrictive, not much reason to get too carried away.

Thanks for the info. The D44/55 saw motors only have a 2" bore. Unable to punch out to the smallest kart engine bore of 2.125.(Mc 1/2/5/6/10 compatible) At least without resleeving. Thats too much trouble. Even tho these little 4.4 CI motors run well, they lack a little for kart use. Unless someone ...

Looking for one or two piston/ring sets for the early Mac saws D44 or 55. These fit a 2" bore and will measure about 1.995 diameter, but look just like one that fits a Mc 5/6/10. Oversize will work also. If you have something let me know. Thanks

I have found myself scarce on the forums over the last few years.....been building my cabin and shop out in the sticks deep in the east woods of Texas. To avoid the craving of anything mechanical/motor/wheels etc, I only allowed myself to work on some dinosaur chainsaws. Since my new residence is lo...

REED ENG was very common on the AH-47 58 61 81 82 motors. The 81/82 used an adapter plate REED 436. REED 434 was the dual carb manifold for Homelite or GO Power reed assemblies. This manifold was used on many different brand motors with correct adapter plates.

What snow blower pistons are you using? From the Tecumseh 3hp motors with one piece block?

Those white motors were on ebay for a short while quite a few years ago. There were about 35 available. I wanted to buy all of them, but shipping from California to Texas killed the sale. Are you sure the ports are lower and not the base of cylinder cut down? Just a little curious. Its possible some...
