McCulloch Chain Saws

[2broke2ride]

What type of spark plugs do the more common Macs use? I have a PM 700 that needs one but also wondering grabbing spares for my 110, 2-10, 7-10 should I need to replace them one day (I usually assume that what is already installed may not be the correct one but was "close enough").

Champion DJ7J

Thanks. For all those models?

 

[heimannm]

Or DJ6J or DJ8J...

6 is a little colder, 8 is a little hotter

A lot of folks don't like Champion spark plugs but in all honesty, I have had both Bosch and NGK plug simply fail, not so with the Champion.

Yes.

Many of the older, large frame saw used a different plug, most common was CJ8. The DJ plugs are a smaller diameter, 5/8" hex, and a tapered seat, the CJ are larger diameter, 3/4" hex, and flat bottom with a washer.

The AC are very good spark plugs in my opinion, but very hard to find these days.

Lots of em out there. Use a cross reference to get a list.
I bought a box of prestolite 14F7N off ebay. Still havent used them all. Had 1 failure. Never had any issue with champion either.

The above table suggests DJ8 for the 54cc and DJ6 for the 70cc. Or should I go DJ7?

I also found this for the 610:

I run DJ7J in all of my 10 series, no problems. Not sure on the 610.

So as a few of you may know my love of old yellow saws comes from my father. He had them mainly because my uncle (Dad’s brother in law) grew up in a logging family and they were dyed in the wool Mac men. I grew up cutting firewood with my dad and my uncle, lots of great memories there. My uncle was about as good a faller as I have ever seen in person. Truth is I learned to run a saw by watching him more so than by listening to my fathers instructions. Dad would tell me what I was doing wrong, Uncle would make suggestions in my methods that could be improved. Again all in all I cherish those moments with them both. Dad is gone and sadly Uncles health is fragile. I have spent many hours the past couple years with my uncle trying to soak up as much knowledge as I can from him concerning old yellow saws. I feel its my duty and privilege to be able to keep the ones that I own that belonged to them both alive as best I can. This quest for more knowledge has allowed us to have more time together and honestly has been good for both of us in various ways. It slowed me down a bit from a hectic though self-imposed work pace, and it has given Uncle something to focus on and look forward to.

I say all that to get to this:

Today I was up there helping him troubleshoot an SP81 and as I was about to leave he said do you have a minute to change out a side plate on one of my PM 700s. He said I found a correct plate for it in the parts box and want to take the 805 plate off of it and get it back all original with this side plate. So off the back shop we go, into the room where the saws stay (We have jokingly called them his harem for as long as I remember). He starts looking for the correct 700 as I help. After picking up about four myself and him one or two he says this is it. So I grab it and swap out the side plates. While I did that he was telling me what he knew of the history of the saw and trying to recall what year he rebuilt it. When I was done I said there you go uncle and went to sit it back on the rack. He stopped me from doing so. I said oh, you want me to take it to the shop and we check it over? He said no. I want you to put it in the back of your truck and take it home. I said WHAT? He said you heard me, I said can I pay ya something for it. He said no. I got home, and had a few minutes to mess with her before dinner. Put fresh fuel in her, she would not pop, squirted a touch of fuel up the muffler two pulls later she popped after warm up she purred like a kitten. It was about all I could do not to cry. Yeap I am a crazy Mac man I guess.

My saws are SO MUCH more than yellow and black. They are a reminder of a simpler time in life, when the world seemed much bigger, my troubles were much less, and the men I looked up to were giants.

Probably the best Mac story I ever heard.

 

[knightmax]

SO for guys that know more than me. This SP81 is supposed to be unmolested. all original. Do you see something incorrect on it period wise? I think someone has been into her before.

Nice story, I have my dads Macs and they hold a place of honor here. My 555 was acting up so I grabbed my 700 just like that one and put a couple tanks thru it today. It had been sitting for a couple years and sputtered a bit and then ran great. I have my first attempt at square filing on the 555 but think I will move it to the 700 and continue to play with it. The square file and the power of the 700 make cutting dead dry elm not much of a fight.

I am with you guys on the 700. Have one and it is a favorite. It was my first Mac bigger than my 10-10 lightweight and I fell in love after the first cut in a 20” oak.

Big brother 850 is a favorite as well.

still have a pm 1000 waiting it’s turn on the bench but I can tell it’s completely different so I’m anxious to see if I love it or hate it.

I'm a big fan of the 700, it was 1 of 3 saws I had for a couple of years and it did alot of work.
I realize that there may be lighter or faster 70cc saws out there but hard to beat the toughness of the PM700!

The 7-10 and 700s are awesome saws no doubt about it, but I still can't put down the SP-81s and 850s. I have all the 82cc saws. The SP81 and 850 are just, well what i like and are my go to saws lol. I think I may use the particular 700 in the OP as a replacement for my truck carry saw while traveling the woods. the current truck saw is a 10-10s. My main problem is I look at a little tree and say to self...self that tree ain't big enough for a Mac lol

Let me know what you think on the PM1000. I got one, I will share my thoughts with ya once you get her going and in wood. I have an SP125c on the way to me now. be fun to see how much more saw it is than my 82cc stuff.
