McCulloch Chain Saws

[RandyMac]

Randy, you up awful early. Hope all is well. Ron

I am up late Ron, sitting in my controlroom, pushing buttons.
All is good, thanks Ron, it will get better in an hour though, that is when my weekend starts.

Did you learn a lot from the man with the watchful eye shown in the first picture? I could use someone watching out for me for a change. Ron

 

[RandyMac]

Old Bob was the land owner and my second saw, heck of a good man. He was a cutter, did heart surgery.

Awesome pics Randy! A 82cc Mac is on the top of the list right now. Have missed some decent deals here recently, but my search has had to go on the back burner. Been spending all my extra money on climbing gear. Still have more stuff to get, seems like working with saws is expensive. I would love to see them still available today, but would hate to see what the EPA would have done to them.

Brian, be careful in your search. I've seen some real junk lately, including a busted saw (busted as in an undisclosed pieced together tank and handle), going for way too much. I've been stung myself more than once. If I find something reasonable, I'll keep you in mind but the first pristine PM850 I find is going to our friend. Ron

 

[RandyMac]

I have enough NOS or really nice to parts, including the motor, to make an 82cc to my specs.
It will be lighter and louder than stock.

So you had to keep an eye on him. I find that the more I cut the more concentration I want to give to it; unfortunately unless I cut alone, I invariably have the distraction of others that don't know or appreciate a safe distance/zone. Old Bob looks like he knew where to stand. Ron

Bob had a great appreciation for life and limb, I even had a hardhat on.:hmm3grin2orange:

 

[Brian13]

Thanks Ron. I have seen some of those junkers as well. I am not against junkers, just means it will take longer to fix as long as the motor is good. I have plenty of time to find one. I just keep seeing all the talk on here about them, and I want one a little more LOL.

I know several of the Macs are 82cc. Which one are you referring to in the 10 series?

 

[RandyMac]

Yep, the 10 series. I not positive, I do believe they were the only ones that were 82cc/5ci, the larger frame models were 80cc/4.9ci.

Thanks, Mark. That's what I wanted, unfortunately I've never seen any of those around here. I have a couple of the older 82cc saws but my PM700 is the biggest 10 series saw that I have.

 

[RandyMac]

This is what that series does best, green conifers, particularly pines or true firs, in the 30" to 42" range. They are an excellent medium chainsaw, however, when there were Cedars or Doug Firs, it sat in the truck, a Super 250 will eat it's lunch.

 

[rwoods]

Also Double Eagle 80. A real nice saw with some work upgrades over the older PM800s: no manifold boot - carb is directly bolted to a solid plastic block manifold, DSP valve and an extra skid plate under the boot strap. Ron

 

[paccity]

i'm getting quite fond of these saws for there pwr and weight. not your stereotype heavy old saw.

Question about McC 250 carb

I have a nice running McCulloch 250 and have a question about the carb... Is there a piece missing that covers the end of the carb within the airbox? There's a couple holes and I did not know if there was a part that attaches over the end? My grandpa hadn't started the saw in fifteen years and it started up in no time. Totally awesome saw!!

[RandyMac]

The "spit" guard.

 

[Fischer]

Perfect! Thank you! Now it's time to clean her up!

 

[promac850]

Well, my 250 didn't have a spit guard... must've been not installed in the beginning or it was discarded if/when the carb was rebuilt.

Did this originally come on every 250 or did they not install them for certain years or was it completely random, like some of the other stuff McCulloch did?

Mad Murdock, PM700s are great. I've had one since new - 30 years now. It is a true workhorse. If you love it, you'll love the 82cc MACs. They are racehorses with AV thrown in. If possible you should add one of these to your stable. It is amazing what 12ccs more can do. I don't have a tach but the 82cc MACs also seem to rev quite a bit higher than the 700. 125s are great saws as well, but if you do a lot of cutting you'll use the lighter MACs much more. 125s are easier to work on IMO. Enjoy. Ron

I agree. My SP-81 spools up much faster and revs higher than my PM700, despite having many many more hours on it than the smaller saw.

I have enough NOS or really nice to parts, including the motor, to make an 82cc to my specs.
It will be lighter and louder than stock.

So you found some NOS engine parts eh? Good deal. Can't wait to see that saw up and running.

Thanks Ron. I have seen some of those junkers as well. I am not against junkers, just means it will take longer to fix as long as the motor is good. I have plenty of time to find one. I just keep seeing all the talk on here about them, and I want one a little more LOL.

I just picked up a 'junker' SP-81 for a 'junker' price. Dirty and a bit corroded (no pitting though), with a locked up engine and soft AV mounts. It's complete however, and will get torn down completely, repainted, and reassembled with NOS parts. Randy had been trying to get my NOS P/C for his project (and I don't blame him), but I'd been saving them 'just in case' I found a 'rebuilder' saw. A buddy found this SP-81 in a local shop boneyard and grabbed it for me. I really like running the 82cc 10-series saws, and am glad I'll have a 'pretty' one as well as a seasoned, former logging saw (my runner came from a local logging family). The 'pretty' rebuilt saw will still get ran however. It's not going to be a shelf queen.

My 'new' saw has a 33" McCulloch branded Windsor sprocket tip bar. My current runner SP-81 has a 32" unbranded Windsor sprocket tip. It's funny that those two lengths were both made for these saws. The 32" bar carries better on these saws IMHO. I'd seen the 33" bar listed in a few IPL's before (#91284, and uses 106DL of 3/8), but this is the first one I've seen in person. Haven't seen the 32" bar listed in the 10-series IPL's, yet I've handled a few. I'll shoot a couple pics of the dirty bugger and put them up. Funny thing is that I thought my runner looked dog-eared...................well now it looks 'new' in comparison to the second saw.

Yep, the 10 series. I not positive, I do believe they were the only ones that were 82cc/5ci, the larger frame models were 80cc/4.9ci.

Yep. The big 10-series saws are the only 82cc Macs. Homelite made 82cc XL700/800/900 series saws as well as several 82cc EZ/EZ-6/7-19/600D/etc large frame saws. The large frame McCullochs jumped from 80cc to 87cc, skiping the 5ci/82cc number.....

PM8200 as well. Same basic saw as the DE-80. I've never seen one in persion. Haven't even seen a pic of a PM8200. I have seen the IPL however...

As Randy said, the spitback guard/collector was sometimes bolted to these carbs. Also, the basic HL body casting was used in several configurations. On some saws, the air filter assembly bolted to the back end of the carb. Those holes serve no use on a saw that doesn't have a spitback collector or an attached air filter, but it'd make no sense to have a second set of dies to cast a carb body without them. The mixture needles were also sometimes placed at the back of the carb instead of the side (often on saws that had the attached air filter assembly). An HL will have blank, unmachined hole sections (with 'H' and 'L' cast over/next to them) for whichever needle location wasn't used on that particular carb (be it on the side or at the back).
