Kevin you do anything to the intake/plate on the carbatooter?

 

[Al Smith]

It would be an experiment if nothing else .I'm rather pessimistic about welding a piston and I won't mention what these things are capable of as far as RPM because the last time I did I got the quiz a dozen times a day on Pm's .I'll just let that sleeping dog lie .
I have a piston from an early right start 10-10 my brother in law the genius ran on av gas and nitro 40 years ago .It ain't pretty .Damned thing sounded like a model air plane engine only louder for at best half an hour .Another one bites the dust ,a sacrifice to the piston Gods .

Might advance the ignition timing a bit more. Started at .020 off the key, then went to .030”. Currently at .035”. Snappier and quicker each time, with no signs of going too far.

So far, I’ve thinned the exhaust bridge and widened/squared up the edges, and raised it 2* to 98.
Lowered the intake floor from 60 to 68*.
Left transfers alone at 120*.
Removed the spark screen and drilled (6) 1/4” holes in the baffle
And advanced the timing about 8*

Only 6 ? Pfft
Better add 7 more 1/8 for good measure.

Behind it is better than still in it

He was chasing it down to get back on quite possibly.

Cleaned it up a little and matched it to the intake flange. Wasn’t much

Edit*I was thinking the block.

Yes, drilled (6) 1/4” holes in the spitback guard

Don't have any. You want XS vids. He's the one with happy spinny tools.
My tool bin is still lacking :-(

 

[RI Chevy]

You have not 1 single lightening performance saw???

 

[Stump Shot]

Currently having some troubles with the automatic oiler. The manual oiler appears to work after 8 or 10 pumps, but after those cuts without using the manual oiler , the chain was dry

 

[Dub11]

That's for demonstration only, not for wood cutting.

Billy has a "pro 10-10" in the beginning of this vid. Is that a different animal? Sounds like 75-90 cc saw to me. Mac illiterate ...

No offense to buckin, I like his content. But about any saw can be quick in softwood with a good chain. Stock 10-10 would be quite slow with a 28” bar in ash, at the opposite end of the spectrum.

Yep, i agree. A 10-10 is kinda anemic in oak with a 20" bar. 7-10 24" is max. I cut a 24" pine with my 372 last year and it was a light saber compaired to the oak we have everywhere here!

The "Pro Mac 10-10" was simply the later version of the 10-10 saws and still a 54 cc model.

Same vintage as the Pro Mac 700 model.

This one was given to me by the boys from the local lumberyard. It was covered with fine sawdust from setting in the same room with the dust collector with a leaky sock. With the long clutch cover and aluminum fuel tanks these saws were heavy compared to the earlier models with the magnesium components.

A little off topic, but how does the engines compare of the Pro Mac 700 to the Super Pro 70?

 

[heimannm]

My impression is the 7-10, the CP, and SP 70 are pretty much on par when they are equally fresh, and the PM700 is clearly behind. I ran my 7-10 with new rings against a like new PM700 and the PM could not keep up with it. At AWOL's a few years ago I had a freshly rebuilt SP70 (new cylinder, piston, new reed muffler) that I thought was rather slow because it didn't make much noise. We ran it side by side with several other 70 cc McCulloch saws and none of them could keep up with it but I did not have my favorite 7-10 along for the comparison. I think all of the saws were running 20 or 24" bars in matching wood.

Thanks Mark. Good explanation. I had my doubts that 10-10’s could be different from one another. Just that throaty exhaust note threw me a little.

It’s true, but there are always those magic saws, I bet there are a few stock 10-10 that have 170+ compression, I don’t own and 10-10’s but guessing 155 is on the low end of stock compression.I have a sp80 with an sp81 cylinder and and sp81 one has 175psi and the other has 155psi, and have heard of a few with near 200psi stock,
