McCulloch Chain Saws

[Eccentric]

Hallo

Anyone knows if its possible to replace the engine of a 640 with the motor 795 to have a
895 then? The gearcase is the same but i dont know yet if the 640 clutch fits on the 795 engine.
Thanks
E.

Yes it will all switch right over. I have a 790 engine that will someday go into a 640 or roached 840/890/895 if it comes my way. You'll have to reuse the 795 flywheel cover and left side bearing retainer as those are specific to the Super Series engines (and the 640 pieces are specific to the non Super Series).

Be carefull with what you do to the ports.
What ever you do you have to do to the
opposite side as well.

Go with .0045 to .005 clearance.

Thanks Lee...

My engine guy is going after this with a degree wheel, no eff'in way I'm touching this thing myself.

If it's that risky, I'll leave it as is.

I am wondering of all the front tank models and years produced what model is the most mass produced? My guess would be the standard yellow top 250.

Not all front tank models were created equal, in the wide variety there are fairly huge differences. The bulk of them seem to be 250s, if you use them as a baseline, power wise you have three basic groups, 4 including the gear-drives. The more modestly powered models are typified by the 200/1-43, 80cc versions. The "mid range" group includes the 1-50/250/300 types. Then on the the higher output models, Super 250s, the 550s and a few others. There are many variants, lots of them only differ in nomenclature and accessories.

I have had a pretty good week adding bits and pieces to the hoard. 3 each of 1-6X carcasses one with long hardnose bar, 1 each S55 carcass, 1 each 33 carcass with bar and chain, PM805 carcass with a nice AF cover, a variety of 20 and 24" 10 Series bars (well used), a nice box of parts like brake bands for the long cover 10 Series, a whole pile of 10 Series brake handles, 1 set of PM700 type rings, 3 each spark plug covers for the front tank saws, 1 each 3-25 diaphragm, 6T 1/2" pitch sprocket for the gear drives, a dozen or so recoil springs mixed between large frame front tank and 10 Series saws, 1 each PM1000 clutch cover complete with brake, 1 each 10 Series clutch (keyed to work with RH nut crank shafts, a couple of file guides, and some other miscellaneous bits and pieces. Total so far is $110...

Then today I was able to stop and see 2Twannabe and got a NOS PM700 piston and a decent used cylinder just for stopping by...

Still on the road mostly for the next few weeks but there will be a whole lot of fun waiting if I ever get to spend time at home again.

I'll put up some photo's when I find my camera again.

Nice haul there Mark. If you don't need that PM 1000 clutch cover, bring it along on your next Indiana trip. I'll trade you something for it.

I will see how it looks on my PM1000, in any case I will have one complete clutch cover with brake extra, probably will be one with a bent brake handle...

This is an odd one. He calls it a "1961 Pro 250". No such animal of course. Has a Super 250 (or 660) AF cover. Also has a black clutch cover. Full wrap too. Earlier 'side kill switch' style flywheel cover (which wasn't used on the S-250). Most intriguing is what looks like a head gasket in one of the pictures. No 250 (Super or otherwise) ever had a removable head. Loomis is over 2 hours one way for me, and he's asking a lot for it (although he has dropped his price a tad over the course of several listings). My curiosity is getting the better of me. It's obviously a frankenMac (but with what engine is the question). Wondering if there's a Kart engine of some sort in there.....

Aaron, I thinking it is a 1-50 series/frankensaw.

I've never seen this paint job on the fan cover, think it's a custom resto?

Aaron, I agree with Randy. It looks like a mish-mash of parts, the heart of which is a 1- series saw. I'd place the value much closer to $50 than what he's asking. What proof does the seller offer that its 87 cc anyway?

 

[Macman125]

possibly a mc 91/93?

Brian the seller mentions doing a paint job on the saw. That's not OEM by any stretch.

I'm with you guys.

No way I'm gonna make that drive for an unknown when he's got that kind of 'pie in the sky' price in mind.

possibly a mc 91/93?

That small possibility is what keeps me looking at the listing every time he relists it....:cool2:

Ah yes, that whole reading thing. Thank ya.

That would keep me interested too. But as previously stated I would definitely try to get it for a better price. Just in case.

Thanks. Desirable at all? Parts out there?

It has me intrigued.

They're not terribly desirable. Mac made a zillion of them over about a 15 year period (the Acres production year info is wrong on this one). They were a consumer/farmer saw made to compete with the Homelite Buz/500, Mono/Montgomery Wards, Clilnton, and Sears saws in the same class.

Most have the 'gravity fed' Tillotson HC carb (as do many of those other saws in the class). Some late ones have a Walbro SDC. They have the same basic 80cc engine as a Mac 1-43 and 200. These have less ports machined in the cylinder than a 250 or 1-50 series (to 'mellow' the power a bit for this price point). They're fun for making noise and messing with at GTG's. If it interests you then buy it, but don't pay a lotta money for it. Parts are easy to come by too...
