Thanks Gregg.
Fuel filter, air filter, clutch bearing and maybe a rim are all in order for sure. I will get a rebuild kit for the catb as well.
I identified the saw with piston pics from this site. It has a 3700 clutch cover and a 3400 starter. I assume the starter was replaced some time ago due to breakage.
The saw is not pristine but appears to have low hours on it. The piston (Al) and chrome bore look great through the exhaust port.
PS got the duck bill. Thanks for the tip.
One of my favorite saws. With the muf. mod they run pretty close to a 4000.
Added 2 4000 style louvers and opened up the diffuser holes to 5/16"
