McCulloch Chain Saws

[Rocker59]

It ain't lookin good fellas... I still can't get this 450 to turn over past about 270 degrees. And I've never seen an engine so packed with gunk, it must have run HOT for a long time.

I'm probably looking at a replacement P&C for this thing to ever live again.

Maybe wrong length spark plug or something like a bolt (or broken points) behind the flywheel?

I took the plug out, but I need a puller to remove the flywheel, it would be great if you were right!

Interested in flywheel puller suggestions for an 80cc Mac??

Something off Amazon or EBay?

I tried the hammer technique...nothin doin.

I’ve used my harmonic balance puller for alot of saws. The Husky puller works well also.

Shown here pulling the crankcase cover but the same arrangement would work on the flywheel with smaller O.D. washers.



I like to leave the nut on, loosened a couple of turns. Those flywheels often come off when you least expect it, and with considerable velocity.

So I should just that style puller instead of buying a dedicated chainsaw engine flywheel puller, thanks Mark you saved me some money, I already have that style puller, just need some long 1/4-20 bolts.

Another tip, get the puller snug NOT TIGHT and give it a good rap or two with a metal hammer. Tighten it a bit more, another whack, etc. If it doesn't move easily I've had better luck with mild tension and shock than with a lot of tension and shock.

Support the saw by the puller when you give it a rap, that will allow the puller and flywheel to remain in place while you drive the crankshaft away from your blow.

Well i got the 795 today. Im happy to say im excited. Very clean, complete machine. No damage. The cylinder is in great shape, the piston looks fantastic. The carburetor has been swapped out with a tillotson hl119 already. Its not a mac carb. I did see a few fasteners missing. The muffler has very little surface rust. Inside the fuel tank is very clean. Other than some little things....i believe it to be a rather low hour saw. Perhaps this weekend ill have it running.
Im at softball practice or id send photos...sorry.
