McCulloch Chain Saws

[rwoods]

MACs have so many interchangeable parts that it can be impossible to determine what model it was at manufacture based on its existing state. If you define model by original ignition a two piece electronic ignition would indicate a SP81e. Points could be 80 or 81. Single integrated electronic coil a PM850. Defined by cylinder open transfer SP80. Divided transfer Sp81 or PM850.

Hey, new guy here. I've been lurking and learning. I wanted to post a photo of my new (to me) Pro Mac 60. I had to get the auto oiler working, but after removing a bunch of sawdust, it worked fine.
I cut up a bunch of fir and spruce with it today.

You asked if "the tank is mounted on the carb". I read too fast. The carb is on top of the tank on this tiller.

What do you mean by "the pick-up tube is a pressure fit? I did replace the end (the part with the screen) on the long metal pick-up tube but there is also a shorter plastic tube going into a little 'catch-pan' in the tank too. Unsure what that one actually does. But I didn't have either of them removed from the carb.

Rob, the fuel is siphoned up the long tube. You replaced the filter. That's cool. But I think the problem lies not with the gasket, but above the tank someplace in the fuel delivery system. Fuel travels up that tube, and the next stop is the needle valve.. Through the metering (needle) valve and into the carburetor throat. The small tube is kinda a new one on me.. Must be a return. The long tube I've seen in plastic and copper.. It is just poked up and in..just thinking maybe got wiggled loose.. It happens. If I think about it tomorrow I'll look a a couple of my carcasses and see what is going on. Been awhile since I've worked on a Briggs.. Without hands on I'm just guessing. I'm afraid I'm not much help.. Just check the obvious and maybe you'll see something. Luck be with ya

That's a neat ol saw.. Plenty o power. My older MACs and Homies get no gas mileage and I'm sure the 80 is no different. But well worth it.. Ran my old 250 today for a while, till my thumb got tired of pumping the oiler..i like to fuel through my saws every once in a while. Don't know if it does any good, but couldn't hurt

My 125's always got much better mileage than my 088 and 880 did.

May just be the huge tank, but my 125s seem to get much better mileage than my 82cc MACs.

I like using my 82 cc McCulloch saws, you get a break more often to refill...



Keep in mind they did not increase the size of the fuel tank when they made the bigger displacement saws to keep all of the parts interchangeable. What started out as adequate for a 54 cc saw was a bit small for the aggressive 82 cc models.

I hate to be the monkey in the wrench but try feeding this thing. I don't run it very often.. Weighs more than me.

Never did I ever expect to find one of these in my collection. Needs some screws, some may be stripped. The front AV bracket has been repaired. (I guess that's why MAC changed it). The handle grip for the under side of the rear handle is missing. It has spark, lots of compression and the P&C look great through the exhaust port. I went to an auction and only one guy was mildly interested (really, he let me have it as he's a good guy) Thanks Jeff!

That is so cool.. Telling the wife it's 123 CCS of power.. Let the games begin

 

[fossil]

It was so cheap she could care less. She listens so intently when I tell her saw stuff but deep down she could care less. What sweetie.

 

[toofuss]

Why can't I ever find one at an auction? Lol. Nice find man

I think it's the only one I've seen in my area. I couldn't believe there was no interest in it.

I hope you're talking about a saw, and not a sweetie

Tim, what's all the fixing and rivets about.. I don't think my 125 will play the piano again, and I might be able to help.

I don't know much about MACs and very little about this series. I'm pretty sure someone (maybe Mark?) said that bracket was a weak link on the AV on the CP models and the SP models got a sturdier bracket. Presumably the rivets and strap on mine would make a believer out of me.

I don't know if the SP bracket will fit on mine or not but there seems to be some available on ebay.

I appreciate your offer but you know how that goes. You'd send something and another saw would drop in your lap. Never say never.

I will need to repair the threads on the recoil cover before I do anything.

Tonight I'm in a saw happy place.
