MCCULLOCH The official McCulloch thread

[Bigmac]

Got some parts for the 797, I had made the best of what I could, put d44 Lower handle and bottom half of the trap door, along with 1-71 wrap handle. Finally found some better replacements

Received a pile of good literature today.

That’s some cool stuff! Nice score. Did the pm105 ever happen? Never seen one!

The ipl pic is like a 797 with sp105 engine and muffler cover, wonder if they made that configuration

that is interesting....this is what it shows here.

This was also a 1973 ipl. August, where the previous pic was September...

Cool! Wonder if anyone has one! I have seen a few 797’s with sp engines...wonder if it was one of those!

 

[Frank bierce]

Absolutely love finding information like this. Now if my thick, pea brained skull can retain any of it....this would be great. Lol

I've got both the big black 20 pound book and the micro fiche set .Problem is I have no way to copy the film into something I can post pictures from . Between the two is a lot of information if you can remember where it's at . Mc Bob sent me the CD he made too which is helpful .
I'm not sure exactly where the carb jet sizes are because I never fiddle with a fixed jet carb ,Really dislike them .In addition I have no idea where a person could even find them these days . It isn't like you can trot on down to your friendly local McCulloch dealer because he retired with the village blacksmith .

Not something you're likely to see everyday.



The one on the left appears to have olive drab paint under the yellow.

Here's another uncommon creation.



According to Mike Jackson, his dad rescued this edger from the warehouse when they were moving from L.A. to Lake Havasu.

So after a wild spring summer and fall i am so looking forward to winter.
I have my boiler heating my house,so my boiler building is warm and my crates of projects are calling.
First up is my Mac 70 that is in a saw body.It was from an old logger from Haines Alaska.It was his play saw for competitions.I got it after it had been sitting for years.The stuffer plate had lots of corrosion so i took the saw apart for cleaning and new bearings and seals.
The seals i got for the points end are double lip seals.So my question is should i still put two seals in on that side.
Plus any torque specs for the rod bolts? or anything else that is important? I have 24 needle bearings for the rod is that the correct amount? Thanks

 

[Al Smith]

I can't talk about a kart engine but on the 125's it shows two seals one lip in one lip out .Positive seal both directions .That said I've heard from people who do a lot of them say they have used one double lip and get the same results .

 

[Yukon Stihl]

I thought i had a Mc 20 Kart engine that's what it said so i never looked close at it.
Turns out it has numbers stamped in the block not Mc70 like the other one.
66019 and 2085

24 Needles is correct. Here's some torque specs I got from one of the guys over at rearviewkarts.com:


torque values
Coil/lamination Screws ------------55-60 inch pounds
Condenser screws ----------------30-35 inch pounds
Con rod - mc49 mc 91 -------------105-110 inch pounds *
Con rod - mc101 ---------------90-95 inch pounds *
*a master mc builder told me told that 101 rod bolts with 85-90 inch pounds and red loctite is bullet proof
and torquing to 110 results in cracked caps.i myself do 85-90 inch pounds
Crankcase End Cover Screws --------60-65 inch pounds
Crankcase Bottom screws -------- --95-100 inch pounds
Cylinder Head Screws -------- --55-60 inch pounds
Exhaust Header Screws -------- ----55-60 inch pounds
Fan Housing Screws ----------------55-60 inch pounds
Flywheel nut ----------------------300-360 inch pounds
Spark plug -----------------------216-264 inch pounds
Clutch Nut ------------------------ 260-300 inch pounds

Getting some saw ready for a 50” bar shootout, and my trusty sp125c was missing in the top end but idled great, tried to tune it a little and nothing...then it died...checked spark, nothing! Pulled the recoil checked the wires, looked good, so I pulled the flywheel and checked the points, all good, then put on a spare coil and it was sparkling again! Points coil down! Put it back together and a new plug, Golden! Need to put a carb kit in the 797 and it should be ready too. Going to try them against a homelite 750 and husky 2100cd hopefully it all works out
