McCulloch Chain Saws

Such is life. The electric brushless revolution has happend now and its very good time to jump in again. Plug it in and go. Lipo batteries are amazing full charge to empty will drop only a couple volts and still go strong. Big stunning planes made from styrene foam are cheap and can be glued up again and again radios are great no more checking who's on what band n bla bla.

I bet there were more Cox .049s made than MAC 10-10s. Came on everything. Planes, boats, cars. My little brother had one on something (I don't recall what) but it had a neat little recoil starter. Ron

Its amazing what rpm those we things can pull 30.000ish from memery

After reviewing the grommets, I am not sure if these were in the HF kit or if I ordered them from McMaster Carr thinking I could use them on spark plugs leads. I am 99.9% sure they are Buna N in either case. Remember that in this case the carburetor had the small nipple so a line with a smaller I.D. would work. In order to use a standard SDC with the larger nipple would require a different grommet to accept the larger diameter fuel line.

I have 2 or 3 of those .049 Cox engines. I also have another Cox engine that is bigger and has the small glowplug. I wonder if they are worth anything now days. I used to have a couple control line planes, a helo, a dune buggy and a GI Jeep with that engine. Those things were great. You can still buy them.

Mark, the Storehouse brand is a Harbour Freight brand.

I checked my box of grommets from Harbour Freight a few mins ago. They did not have a grummet like the one in your picture so I bet you got them at McMaster Carr.

Thanks Poge, That is a very handy thing to have laying around.

And so comforting to know that our carbs are made out of incompatible metal. LOL

Done a little cutting today on a tree that was taken down behind my shop. Gave the SP125C a little exercise. I have got to put the screen back in the exhaust. The stump is setting on some brush and caught it on fire. Good thing I had a water hose back there.

Fire, just another thing to add to my worries when you are unsupervised.

I bet the more you run that 125 the more you like it. Not much fun to lug around though. Hopefully, we can find some wood and the time to gather some baseline in the cut rpm data for our 125s and 800s.

You are right on all three accounts. It is heavy but love how nicely it starts and how well it cuts and we do need to check RPM and I do need supervision...lol. I keep the tach in my chain box, I just forget to use it. Mine was just a little rich for some reason today. The last time we was cutting, the bottom end was a little lean and I richened it up and I think it effected the top end as well. It just needs a touch. It would be alright the way it is but I like them to be spot on. Such a smooth cutting saw. Once you get it placed on the log to be cut it will just cut by it's self. Very little effort. It just keeps going with very little effort from the operator.

Anyone have a scored but otherwise good PM8200 cylinder with crankcase, they would sell me? Ron

Nice fit on this 7-10 muffler cover. You'd hardly know it wasn't factory

 

[rwoods]

Watch you leg with that thing. I branded my chaps with the GEM muffler on my 125. Ron

It's from a for sale ad. The guy wants $150 for it, doesn't run a few things missing. It would be better off with a piece of truck flap waving in the exhaust stream

 

[rwoods]

I thought you had picked up a new saw. Maybe it will find a good home and get a muffler mod. Ron

Okay. How about a not scored PM8200 cylinder?

[vinnywv]

Not a very common saw. Im sure theres a cylinder out there somewhere. If its any help the part number is 300740.
Once you find one though...what a nice running saw. Good luck.

 

[Jethro 2t sniffer]

This probably mite get me a back hand from my mates but....
Its not too far away from the right shade of yellow in the sun

 

[vinnywv]

Matches the 700 pretty well. I like it.

Cheers was 1 percent of the cost of a real mac hard hat and is more useful just got the decal made down at the local sign writers

8200. Lots of power. Needs a FW side seal I suspect as it went lean on the second cut. Comp is 175 psi.

Will be looking for a new brake cover. This one's smashed in the muffler section.
