I'm all cranky, first cup of coffee in progress.
That McCulloch guy from last weekend dropped by while I was
asleep, yep, I slept through it, even the racket caused by the pups
didn't wake me up.
I'll head over there after lunch.

Went back out and worked on it a little more... I noticed that the piston traveled smoothly until the rings got somewhere above the exhaust port... I don't get it, usually the piston moves very easily at the top of the bore, as that is the area where the rings wear down the plating from use. Anyone have any idea what could be the problem?
Sorry guys, I have been traveling a bit and away from the good old USA, France last week, this week in Japan and Thailand, next week on to Vietnam. I will do my best to stay in touch.
RH start big cube McCullochs, D-44, 44A, S44A, 1-70, 1-71, 1-72, 1-75, 1-76, 440, 740, 790, 795, 797, S797.
No fair getting the 1-72/75/76 or 797 before I do...
PM610 - are you absolutely sure you have the ring end gaps located over the pins? I had some trouble with this on a 5-10 project a while back but finally when it went together, it went well.
I'll do my best to check in from time to time, have fun in the mean while.
And all the way back to the gear box oil question, McCulloch sold Mobil "C" 140 for their big gear drives. If you look carefully on the shelf above, Hoimelite used 90W.
I use 80/90 or a semi synthetic 70 in mine now. No problems so far but I don't generally run several tanks through a saw in a day so heating is not too much of an issue.

My guess would be the same thing that Mark stated; One of the ring ends has is up over the allignment pin on the piston.
Crikey Randy. Go take care of business ASAP!!!
That photo is fantastic Mark. Is that an NOS saw? Super 250? All of that McCulloch goodness on one shelf. I like seeing the OEM wrench tied on the full wrap handle. Fixed your "no fair" list above.^^^ You don't have a 790 IIRC...:msp_flapper:
That saw is my 650, runs but leaks a little fuel from the tank gasket. I had to rebuild it from the ground up, still not 100% original but looks good setting there.
RE: McScrentch - The one tied to the saw is the stamped version, the one on the shelf is an original forged one, both bear the McCulloch markings.
I have had good success in my travels finding interesting stuff. Somewhere I have a McCulloch File-O-Plate courtesy of Jeff, but there is another style out there with an extra wire bale on it, still need to find one of those.

Yeah, I set the rings in the proper position before I installed the piston. Since the two have been introduced to each other for a while now, I'll go check on them...
I went out an checked it, the rings are in the proper position, looked at them by sliding the piston up to the intake port so the rings were visible. The ring ends are exactly where they are supposed to be. Also, the resistance of turning the flywheel by hand has gone down, I suspect maybe they just needed to be together after being apart for so long...
I hope that this is not another stupid question.... lol.
I am putting my SP 125C back together, and I was wondering how necessary are the chain guides? My Husky's, Stihl's, and Jonsered's don't have them. The chain guides definitely make it a bit tougher to put together. Maybe I just need practice...

Chain guides? Are you talking about the ones that go on each side of the bar, or some other kind?

Went out and tried out the 10-10 today. I think I need to rebuild the carb. It would bog down in the cut like it was flooding regardless of the settings. And I noticed that the muffler was pretty wet with unburnt fuel.:bang: This saw if fighting me tooth and nail, probably should have rebuilt the carb to begin with but everything looked ok.
On a side note, if you use wood to grill with and run out of lighter fluid, Bacardi 151 will work as a substitute. And as far as I am concerned lighter fluid probably tastes better, so I didnt feel bad about using it.

Oh yeah, break out the rye.
I made a deal on a cherry PM800, should have it in acouple weeks.
Looked at two 48" and one 72" Mac bars, old solidnose, will need dressed. The guy apologized for the chain, it was half used full chisel 1/2 inch. I don't know when I can get these, but I will and you can't have any :msp_flapper:

I am toasted
