MCCULLOCH The official McCulloch thread

[hacskaroly]

Their buddies had never seen how well a properly tuned old McCulloh can run .

That is one thing I am finding, the older saws are fun to work on and can run really well!!

Finally back from vacation and got word these diaphragms and other gaskets for the 3-25 I had been working on are complete. I have a few more little items I'll be adding to the kits but for now I have these two products posted and ready for purchase.

Picked up a couple of old guide bars today. Two of them are McCulloch, one of them is a Remington, the one mocked up on the 797 I'm not sure about. The part number in the picture is of the Super Pro bar, I can't find much information on it.

86882 Bar, 28" Super Pro, .058 List $27.25 in 1973

Would be $199 today correcting for inflation.

SP 81 cylinder (sleeved), I used a PM 850 tank for testing while the Red Kote in the 81 tank cured. The first saw I put together with a sleeve would run 90 seconds the die from lack of compression. When is cooled down compression would come back up to 140 PSI or so. Repeat...

This one seems to work O.K. I ran it for 30 minutes or so and is seemed like the compression kept getting better. I used an 850 muffler since I had the parts available.

Friend dropped off an original sign.
Its painted on steel sheet.

I smoked an 805 engine by using a prime of straight gasoline .My mistake from not paying attention .Replaced it with doner from an early model 850 .The original engine because of the year it was made just so happened at the same time hard Rhodesian chrome was in short supply because of political unrest ..To repair it I used a block from a later model 850 cylinder but I had to do some modification .If memory serves that was because of the way the coil fit .Thinking back I think I had to shim the coil outbound so it hit the flywheel dead center of the magnets .At any rate with the complete 850 the saw runs great and cuts very well and basically looks just about like brand new one .However it's a shelf queen to preserve it as I certanly have other saws that run well .As for the engine I ruined the block can be saved,the piston is toast --parts are parts .

 

[Al Smith]

Regarding a sleeved engine I've only done one for a 125 Mac .Bored the block out 70 thou and turned the sleeve from grade 50 cast iron which BTW is the same alloy used by Harley Davidson .Honed the sleeve with a Lisle precision hone to a 4-4.5 thou fit.That BTW was not a few hours job ,it took weeks . The saw runs great but again another shelf queen .--

Over dramatic but this video does contain a lot of good information. You will have to excuse most of the photos and illustrations as apparently whoever put it together did not feel it was necessary to accurately represent what they were discussing.

Watch for the guest cameo at the 2:05 mark...I had no idea...

Our local newscast always runs footage of a sewage plant, whenever they talk about drinking water or the supply pipes.

Unless it's the pocketbook or shoes on some famous for being famous sort of person.
I don't think anyone in media production is paying much attention facts anymore.

Wish I could make it Mark, sadly the schedule will not allow it.

Found an old model 35 in a barn today. Worth anything or a boat anchor?

I think it is cool looking with the funky recoil, the bar sits a little erect compared to normal saws!!

 

[LAWN BOY]

I've had a couple 35s and also have a 39 and a 35 brush cutter too. It worth more than being used as a boat anchor.

 

[S&S_Work_Saws]

Same thing with this one. No idea anything about these old yellow saws.
