What's on your bench?

[heimannm]

Someone sent me a Facebook listing for a local saw, I'm not on Facebook but I showed it to my son and the saw arrived on my bench the same day. The tag on top says Lancaster.



The paper label on the side says Dayton.



We pulled it apart today for a good cleaning.



Looks better now.

Did some tab adjustment,

Got the saw to run fair until it is turned on it's side.
Replacing both seals next, flywheel side

Clutch side.

Cylinder cleaned up great, with the exception of a few small gouges/scores in the plating up top. Didn't go through, and they were barely noticeable with a pick scrape, so I'll run it.

Modded muffler outlets on the side into one large outlet. Front outlet was opened significantly too.

Now I'm just waiting on a 3-shoe clutch and some decals from Sugar Creek.

Added a fuel filter to the Mac 250. Hose was there but the filter material was nowhere to be found.


Starts on choke and idles for a short while.
I suspect that it may need some carb work, but I will let the fresh fuel and oil rehydrate the carb diaphragms and see what happens.

Even though the serial number suggests it should have the later carb (more square lower carb body), this one has a very circular bottom end.

Sounds pretty sweet. This is my first larger Mac.

Your saw has a Tillotson HL carburetor, the others have a MAC (Walbro) flat back carburetor. I think the flat backs are more responsive and run harder, but they can be more difficult to get adjusted correctly.

A late model 250 should have thin rings, they did seem to run better that the earlier thick ring models.

Yep sure looks like a pair of thin rings. s/n in 2nd pic.

I have a Super 250 that hasn't been started in a great many years now.

Thanks for confirming what I had found for the carb information.

I was really surprised that it started popping off after 5 or 6 pulls with just a small prime. After the initial run, I could restart with the choke in 2 or 3 pulls. It has only been fueled to about 1/2 tank as well.

If you do a Google search you can find the large fuel filters .Which very seldom clog up .MFG Supply at one time had a collection of OEM but I checked and no mention of of them now.

Bought an original Husqvarna flywheel puller. The trick with a punch and hammer (and heat) doesn't work every time.

Also got the seal installer sleave. Makes it very easy to change the seals on 61's and 266's. Not sure of they work on other models.

Not on my bench, but in the hangar. Some pics from my morning job.

My new best friend Woodwackr made this available to me.



The package arrived last week and I was able to get it opened up today. Taking it down for a good cleaning. Has spark and the fuel tank is very clean, if I can get through the Carter carburetor without any problems I may see about getting this one to run before I hang it up in the display.

I’ll be curious to see how you repair that rotation collar. Weld up the worn hole and re-drill/machine?
