Thanks for checking your surplus parts. I needed a set of rings and found them a couple weeks ago. Next is digging out everything and seeing what else is missing. I forgot the D44/55 had a smaller rod journal. Never had a reason to tear one down, except to remove the head and shrouds. But this saw i...
Getting rid of the stock intake and reeds will make a huge difference on the saw. The Mc49MC for its original use came with a BDC 22 carb and ran pretty well. But the HR Tillotson I had in mind only has a 1" venturi. So it may be worth a try. if I work out a decent reed setup, should work fairly wel...
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" ...
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.
