McCulloch Chain Saws

[MacAttack]

As they say in Canada...pro-gress.

Compression feels huge on this saw. I'm looking forward to getting the recoil on and testing it.

I think my 125 has an air leak??? What is not in the video is several restarts and the 125 revving up. The last few seconds show the revving up. It had been a year since last running it and it ran fine then. It might be time to to pull her apart for a refresh. Compression on this saw can be painful!!!

Here's a random one... and I'm not very concerned, but does anyone have any idea where this 2nd felt block is supposed to go?? It's in the IPL (#27) but I sure have no idea. It fell out of the recoil cover when I cleaned the saw... it's not the points cam wiper.

Lots of people spell it aye... which makes them look Scottish.

I learned that from my Canadian coworkers and their pronunciation of "progress" stuck in my head so much that was how I started saying the word myself. Here in Buffalo we say PRAH-gress haha.

Just wanted to post a "Thank You" to all who have supported me for this first year of my "Old Saw Shop" business experiment. Your support has been appreciated.
The people I've connected with have been great...Most are selfless, and willing to help in any way to promote the good of the hobby itself. It's getting harder to find that sort of environment, so again I'll say Thank you to all that have helped me out be it with questions, or purchases (or both).
I'm looking forward to another year of creating new products and helping the hobby.

Andi - that felt is a "seal" (breather if you will) . I believe there is a vent hole in the vicinity of the breaker points box, maybe under the condenser??? I don't remember where it goes on those models.

On the super series engines there is an additional "strap" that holds the felt against the points box. See 19 & 20 in the illustration below.

Thanks Mark!

I got the clutch and flywheel installed tonight. Next is the coil, side cover, recoil. And I'm going to attempt to rebuild and use the Mac Flatback carb and see how it runs.

I stole the flywheel off my 250 parts saw since the 450 flywheel is missing a recoil pawl.



You were 100% correct on the wick breather....it goes into a space under the condenser to cover a breather hole that leads to the inside of the side cover near the oil seal:

Any thoughts on a replacement???? Pro Mac 1000. Seems to have a weak spark.

I used a 266 coil and it took care of the old spark problem

I'm happy tonight.... the 450 has a bright hot spark, and the compression test has me grinning from ear to ear.

Once the carb is rebuilt this baby is gonna make chips.

150 PSI on those is excellent.

You'd better start using a gripper with your left hand now to build up your strength, you're going to need it.

Haha!

The first time I gave that 450 a pull on the recoil with a plug installed, my first thought was " man...this saw is going to be a bear to pull over!"

Especially without the wrap handle installed...I was basically doing a pushup on the saw with my left arm and pulling with my right.

I'm more than a little anxious to see how this saw pulls the 24" bar.

 

[bob kern]

This all reminds me of a 380 I have waiting in the wings. Maybe it will get it's turn on the bench now that the pm 1000 is making chips again.

 

[MacAttack]

I think a 380 and 450 are almost identical with the exception of the automatic oiler on the 450.

Close enough. That statement could be made for any of the front tank saws. Once you go through one, others are easier. You will find plenty of differences and similarities.
