I was hungry and ordered a Big Mac.

Finally showed up today! Model 1-80. Runs to...needs a kit, fuel lines, cleaning and tune up. Outta work real nice with the 36" hard nose bar I have sitting along with a .404 conversion. May throw a 52 roller nose on there if I can snag the bar soon. Has 170 psi and possibly a cart engine....any particular way to tell? Has the removable head. I'll keep following up as progress continues...may receive a repaint and restore.

Yes it's a kart. With the gear drive you'll definitely want a very long bar.
I have the direct drive version of it.

There were several of the early saws with removable heads including all of the 44/55 models, the 1-70/80, 1-71/81, and 1-72/82.

A removable head doesn't necessarily mean it's a kart motor. The kart motors have particular port timing numbers.

The numbers should be on the bottom of the stuffer for identification .

Out of curiosity, is it possible to match the port timing of a kart motor, in a non kart motor?

In some cases yes, but on some of the motors like the D-44 it's not going to be totally possible. This has to go with how low in the block the exhaust port is cast and the early kart motors have boost ports, which the saw motors do not have and there's not room in the block to make one unless a person welds up material. Upgrading the intakes really helps a lot on the saw motors.

I was searching through some photos this week and was reminded where my beautiful 1-80 came from, thanks again to Ike Holt!



I took it to the Mastermind GTG last October and made a few cuts, you can really hear the air vane governor working if you don't keep it loaded.

Like JJ mentioned the two boost ports were on the intake side of the engine . I've got a derelict super 44 that Dan Henry sent to me I have plans to try to put some soup to it .It's another one of my back burner projects .I just wish it were a super 44A .Then I'd try to turn it into an MC 10 .
The way I look at it is like this. If it's decent all intact machine machine leave it stock .If it's a salvageable junker lay the soup to it or use it for parts . It doesn't make much sense to take a 75 dollar saw,put 200 in it to have an 80 dollar saw .

Been looking at some of those over bore pistons to lol

After some cleaning, a carb kit, and a .404 conversion she rocks a 36" hard nose really well.
