well Jim, i guess you'll have to punch out a LG6 or G70 to make it 82cc.

I will keep my eyes out for one as mine is only 54cc.....even though there may be enough meat in the cylinder too...........Hmm, I may have to call my machinist buddy, I need to call him anyway so he can make me some V-stacks.

After spending most of yesterday and the previous two Saturday mornings falling a big busted oak*, I was asked by my wife while we were driving up the driveway after church today when was I going to cut up the three downed trees in our yard. I told her some evening this week when it wasn't raining. I took refuge in the chainsaw lab and began reassembly of my favorite PM800 after replacing the oiler knob I broke a few weeks back. I put an 8 pin on it. By then it had quit raining so I took it for a little spin. Seemed to run better the more I ran it (it has less than two tanks of mix since rebuild). But it took 1 1/2 tanks just to buck up the three little trees. Sure seemed like a lot of gas after running a strato lately. I know these saws are thirsty but I found the auto oiler wasn't working. I finished the job using the manual oiler and did almost as much work on a half a tank. I am game for running a little kerosene through the oiler - bad idea???

Ready to go:
Yes, that is a new half wrap. Much easier to replace chains.
Posing:
First tank - about 75 cuts plus a little fiddling:

Does the anti-vibe really work? You would think I had been running the PM700.

So what are we saying?? Need a G-70 to make an 82cc saw? Will it fit without modifications, just bolt it together??

You may be able to bore out that g-70 to 82cc but you can't just bolt on the gear unit to a 82cc saw. The gear drives use a special crank case and crankshaft. I had dreams of building a 82cc gear drive but its starting to fizzle out.

This summer I was having a devil of a time with the flatback carbs when it was 75* plus and high humidity. The Super 250 was one of those giving me fits. It sat on a shelf, untouched since. I grabbed it today and, with nothing changed but the weather (high 40s), it ran great. Further proof that my Macs do NOT like hot, humid weather. Suits me fine.
Muckin' about with a pair of old 87s.

McCulloch 450 & 33/35
I recently got these from my dad. They aren't in the best of shape, but they are interesting. View attachment 256296View attachment 256297
I've been debating about keeping them or trying to get rid of them. I'm mostly interested in the 450. Where can a fella get parts for one of these? I know that I need a spark plug and muffler. If I can get it to run, I'd like to get a new bar and chain. Since this is roughly a 90cc machine, what can I run on there efficiently? I'm thinking 32" or so...is that feasible with something so old and yellow?????
Any & all thoughts are welcomed.

Very nice 1-61, I bet it cleans up and will look almost new.
That decal is in mint shape. That saw hasn't seen a whole
lotta use.

Way to go Dave. You Suck!
That's the second McCulloch gear drive that you've gotten a great deal on lately. With your 660 and 1-61 plus my 650 that's three McGeardrives that have been harvested from the SR area.
Now you have throttle/choke linkages to copy when you modify the flatback application links on your 660 for the HL63 I traded you. RK-88HL is the kit you need. 3/16" ID tygon type line in the tank and 1/4" ID automotive line for tank-to-carb.

i was searching for more info on the 82cc cylinders this evening and thought i'd post my findings. we all know that Mac used "A", "B", "C" pistons and they must match the cylinder but little has been posted about the jugs.
the pro mac 8200 used a different cylinder, piston, crank, and maybe other parts. it is listed as having a "high silicon piston". anyway, the piston is part number 300687 and the cylinder is 300740. it was only electronic ignition and no de-comp. it has the "Q-port.
i tried to find differences between the A,B,C pistons but all my IPL's show the "C-case" cylinders. the part numbers are as follows:
215713 is listed as a "C-case" and was used on the super 850, PM800, DE80, 805. it was used with electronic ignition and came both with de-comp or with out. the de-comp was located on the exhaust side. it has the "Q-port"
95167 is also listed as a "C-case" and was used on the PM850 with electronic ignition and the DSP on the rear
87296 was not listed as either "letter" and was used on the SP80 with thin rings and thick rings. it was points ignition with the rear de-comp
93265 was listed as a "C-case" and was used on the sp81E with the rear de-comp
92450A was listed as a "C-case" cylinder despite having the letter "A" in the part number and used on the SP81 with points style ignition only and rear de-comp
214740 is also listed a "C-case" cylinder and used on PM800 saws with no decomp and electronic ignition. it has the "Q-port"
please add to, correct, or take away if needed. hopefully this can be helpful to someone.
Info from Aaron: I have a #92450D "Cylinder/Piston Kit". I don't have the original box however. The #93453-R1 Instruction Sheet (in FIVE languages) states that this kit is a service replacement for Sp-80, SP-81, SP81E, and PM850 saws.

I will hang on to that informtion Joey, good stuff.
I found a piston last week with a part number 87791. It was the same basic dimensions as 92518/519/520 ("A", "B", and "C" pistons) used in the later 82 cc saws. Looking through my IPL's I see is belongs with an SP80 with serial number 14-XXXX.
McCulloch did a lot of crazy mix and match, often makes it very difficult to state any hard and fast rules about what part numbers go where.

Is that the thick ring piston? I've never seen one. I do have the thick rings though for the SP80.
I will have to look at it again to be reminded, but I don't remember it being a thick ring. I had a 92519 and the 87791 in my hands at the same time and it did not register that the rings were different.

Mark, do you know the part number on that NOS cylinder that we think is a PM850?
