1st time McCulloch owner, Pro Mac 850, couldn't believe it fueled it and it fired off easily and runs good.

Is it missing a muffler cover of some sort?

Ur first one , is one of the best ones .

im looking at it sitting on my tailgate, resisting the urge to wake up my wife piss reving it.

You are starting with one of the best saws McCulloch made. Muffler is correct as it it, but may be missing the reed (item 68) under that guard you can see. I have some reeds if yours is broken and you'd like to replace it.



Also, someone had cut off the back half of the clutch cover/brake assembly.

More progress on the 1225. It runs, sort of, but without the bar and chain the engine can overspeed causing the screen under the starter to flex and contact the starter housing...







I have resisted adding the bar and chain since it has no provision for chain oiling...I guess I will just have to figure something out.

I do have the muffler back together, a better torch would have made the job a lot easier and neater but I think it will work for a few demonstration runs.

I knew something didnt look right, and now you mentioned it, I can see where the clutch cover has been cut, I do appreciate the info.

Will not affect operation at all. Just not 100% correct. Use a good oil mix at 32:1 in the saw. They are chrome bore, the cylinders and pistons are ultra rare and basically non exsitant anymore. So 32:1 is important for the longevity of the saw.

 

[redneckhillbilly]

I dont plan on keeping it, as much as I like and appreciate the old stuff, I just dont have much room for collecting things that wont get used on a regular basis.

what do you guys think is a fair price to ask for that saw?

I prefer a 16" on the 10-10 models, maybe 18" on a PM55 or 10-10S version. I have everything you need except the clutch cover/brake assembly and I may have a decent used one of those; I will try to remember and look next time I'm up in the attic.

More progress on the 1225 yesterday, engine is fully assembled and we have a good strong spark. I ended up swapping the shroud from a 5-49 in the attic as the one that was on the saw was badly bent up. This one actually has some paint left on it. You really must assemble these in the correct sequence and be careful with all of the "captive" nuts behind the screws. Many of the nuts are no longer captive and like to fall out before you can get the screws installed. I did use some glue on a few, including the bolts for the recoil starter. The shroud goes on first, then fuel tank, then flywheel housing, then the starter pawls & screen, then the starter itself. Not. perhaps. the best planning on the part of the engineering team at McCulloch in the late 1940's.

I like the grey and yellow, it looks kinda steam punkish to me .

 

[heimannm]

Swapped the screen from the 5-49.



Added bar & chain to avoid future overspeed conditions.



Ran it for a bit this afternoon. It is not what I would call reliable like the 99 is, but I can make it run. I added the helper handle as a finishing touch.

The transmission (gear box) is back together.

I've been looking into McCulloch two man saws...

1225 1948-1948 7.9 In3
5-49 1949-1951 7.9 In3
7-55 1951-1953 9.8 In3
99 1954-1963 9.8 In3
1-92 1961-1962 6.3 In3
1-93 1962-1963 6.3 In3
940 1969-1971 6.3 In3

4 down, 3 to go

Great info mark.... Please share further discovery if you can.

I'm trying to make heads or tails of these saws as well..... Thanks to help from Chance Wold, I have many of the components including transmission shims made made. So far I have a 1225 with the smaller carb casting, and the 7-55 with the larger carb body, and the D shaped diaphragm gasket (24945). It appears from your earlier post about the diaphragms that they may have been more of a mix and match but if I can, I'd like to establish a standard (X goes with Y). Right now its all on visual inspection, and it would be more clear if we could define what came with what... The IPL I have has not been clear. It covers several saw versions but is vague when it comes to the diaphragm types. Most other differences are made clear however. Guessing it was early for McCulloch so IPL's were not as standardized as they eventually became.

The the #18199 has the vent in the cover.
The #24945 does not but on the rare occasion there is a #18199 that does not as I've had to exchange a few for a couple of customers. There was also one occasion where a a #24945 had one, according to a customer, I can't confirm that just did an exchange.

So much for consolidation of versions Eh?

 

[heimannm]

The IPL also calls out the same carburetor to saw gasket but as you can see looking at the two carburetors, they are definitely different.

1225 / 5-49



7-55 / 99



The primers are also different between the two.

Jeff - take a look at the 7-55 carburetor body I sent you and you should find it has the bleeder vent.

First time tearing down an older McCulloch today.
McCulloch put a lot of thought into hiding fasteners and slot head screws work.

That isn't a box to throw away is it? That would be a sad day!

Nah. So far so good.

Definitely differently built than a 2100!!
