This one run "special." It blew away most of those I saw on youtube. Far more rpm's and power even though the compression was so low.

I started using a dial indicator to find top dead center, it's alot faster for me than a piston stop. Taking the readings, dividing by two subtracting from the reading from the stopped position, moving the wheel and trying it all over again. I get top dead center first time with the indicator.

Now this saw had a crappy worn out carb and I replaced it with a chinee copy and deleted the governor. It was already wearing a midway exhaust trumpet on it, similar to what you would see on a kart engine.

Do you know approximately when that saw was originally built? Never seen one in person.

Thanks for sharing. What was the thinking "cutting" the piston instead of jug? It doesn't seem that much easier to me.
