No picture....it's a V-12 reed block with a burris mikuni, not an HD Tillotson. It had twin HL's when I first got it which actully set up better on the V-12reed block. Short header with a spun kart pipe. At one time it was a National winner, supposedly dyno'ed at 22hp.....Take the 22hp with a grain of salt.

Would that be this saw. HAHA
I own the old kart that Dennis was talking about.

And it is on ebay this week.

Here is a picture from 1984 of my brother Dennis Holmen competiting with his Mac 101 at the Prince Albert , Saskatchewan Winter Festival here in Canada. The day of this competition it was -41 F. below , talk about survivor series!At -40F saws get good hp [more dense oxygen in air]

His time was 5.13 sec. [cold start, 3 cuts all down within 6" of log] in a 10"x10" frozen spruce log. This was 1 of 3 saws that came to our neck of the woods from Bob Walker of Walkers Saw Shop in B.C. [Walkersized]. Its stinger is inverted inside the pipe.

In the last posts picture I displayed notice the guy behind Dennis with the sunglasses and grey beard ,thats Gary Walrath of Iron Horse hotsaw fame.Gary being a PNW man didn't feel comfortable running his own hotsaw in -40.

I can't say for certain but Jim Taylor sure sounds familar. May have competed with him up at Sayward on Vancouver Island ,B.C. I never ran the Macs but my brothers Dennis 60 yr and Cliff 62 might have met Jim and Doc because they both had 101s and have been around about 10 more yrs then me.
Interesting note here. In 1972 Woodsmen's Carnival in Galeton,Pa.,introduces an unlimited chain saw event,[ the grand daddy of hotsaw competitions.]

Keihin, what is your point?

The SP125 will not make 30 HP.

The SP125 will not make 22 HP.

Spare parts are rare.

You are bothering Dennis and Mac Daddy.

If you want 30 HP, build a bikesaw.
