The farm where I work as an 021 just sitting there doing nothing. It's been used but replaced with newer, larger saws. Now, I don't NEED another saw but if the owner wants to give it to me I guess I'll just HAVE to take it. I know nothing about an 021 except that it is a smaller saw. What can you kids tell me about it?
Clamshell design, 42.5mm MS250 topend should just bolt on, AM parts like carb, coil can be had cheaply. If it's newer and similar to the MS250 that I had apart - fuel delivery is way overcomplicated - 6 fuel lines, 2 Ts, and bulb to get fuel from the tank to the carb.
