2-10PS pictures
Now that I've settled down, time to share some pics of my new 2-10PS. The PS stands for Power Sharp, an on-the-saw sharpening system. It consists of a mechanism mounted to the bottom of the crankcase that has a little curved stone to sharpen the special duo-sharp chain. There was some speculation how this was activated when I first posted about this saw, before I had received it. It is brought against the chain by turning a locking screw 1/4 turn which releases it from the stowed position. The saw is then run at 1/2 to 2/3 throttle for about 5 seconds to sharpen it, then the stone is stowed away again.
It even came with a brand new replacement stone
Here is the chain
As are other self sharpening chain concepts, I imagine the convenience is offset by poor cutting efficiency. In the box was a hand written note, presumably from his repairman, and it says "Mr. Colbert, I would suggest that you replace this chain which is designed for self-sharpening, with a standard chain. I think you would be very pleased with the increased performance of your chainsaw" It goes on to suggest a couple types of then available chain that could be used.
The box was another story. I don't know that I would use it, but it's too nice to just pitch it. It's made of plywood, has a piano hinge lid, carrying handles, and has aluminum tracks inside that guide the handle in and hold the saw in place. There was even a spare roller nose bar, but it had been braze repaired but does appear usable.
The owner was very meticulous, he probably was an engineer or similar type.

More 2-10PS pictures
Here are some over all pictures of the saw.
The carburetor has an adjustment mechanism that I haven't seen before. It is adjustable from outside the air box, but the screws are all in a row, and connect to the carb with a little flex joint.

I was expecting a flat back McCulloch carburetor :msp_confused:
Very nice find Jim. I don't have any PS 10 Series in my line up yet, but now know I have to look for one...
I do have a mostly complete MM with the auto sharp system, as well as a couple of NOS chains. I also have a 300 Series with the AS but that one will be scrapped or give away.
It is nice to have a piece of history now and then just to show others as well as ourselves how far the industry has come.
I have some of the Kolve wing and raker chain, really makes a smooth cut but is not as fast as a modern square chisel sharpened properly.

I am truly grateful that it doesn't. It seems most of the 1-10 and 2-10's I've seen do have the bullfrog.

The flatback and bullfrog are two entirely different carbs. :biggrinbounce2:

Was the flatback used on the big saws and the 10 series all have the bullfrog?
On eof the REAL experts will be along .... I have a bullfrog only on a 1-10 I have, but have flatbacks on some older large Macs (440, 250 and I think the S550).

Bullfrogs are a 10 series thing only and the 2 are mutually exclusive.

I only bought one of those... now the 7.5 stuff on the other hand...

Any change in the 1-40 and 1-42 saws, or are they still in the under $50 range?

Made a new sprocket and gave her a new 1/2" chain.
Also swapped from flatback to HL with choke.Starts,runs and cuts great!

Really nice!
How long is that bar?
Bar is 32" (80cm)
1-42 80cc old iron
Hi folks,
Sort of had it running tonight, but obviously needs a carb kit new lines etc.
This is a new carb to me, not sure what it is, certainly different from the one on a 380 that I sold last year (big mistake) Fuel line to the carb looks like one from a car!!like 5/16 id or so. Hopefully carb kits are available and not unobtainium! The muffler shield is broken and I've not had it off to look at the P&C yet. Photos to come. It doesn't look like it has worked too hard, very little paint gone and little off the bottom.
Regards,
Lee

1-4X models should have a Tillotson HL, kits are readily available. If you end up with a replacement fuel line, make sure to use a grommet where the fuel line passes through the air box.

new find 1-42
Thanks Mark,
Mine is missing the grommet for the carb adj but the fuel lines look OK. The carb needs tidying up I'll need to order a HL kit as locally they are expensive. The muffler seems shot, can't remove it easily. Fuel is leaking from the carb when I shut it off. Not sure how to have the pics in the post rather than just as file names. Great forum, have learned lots just read as well as asking.

I used to own one of those 1-40something saws and got the opinion they were hard to start. I recently got another one, cleaned the carb, set the points and this 1-40 and my 1-42 are as easy to start as any saw I've owned. I guess it's all in how they're cared for.
