I got some rings in for it but it's going to need more than rings. Jug has worn thru the chrome plating.
More pictures to come. I've got to go chop kindling before it gets dark while the photos download.
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.
I got this arborist hooked on my work when he came by to do a quote for stump grinding. We chatted a lil', then I had him run my ported 394. Being a stihlhead, it make to much of an impression. Then I had him try a ported 064. He' been a steady customer since.
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.
