Some of what I've read says if you don't hone, the saw will smoke a lot until the new rings seat. Others say just scratch up the clyinder walls with some 600 grit paper & they'll seat faster. Myself, I always run a hone in, with kerosene for lube. It may be only a few passes, it just makes me feel like I did a better job. I've never had problems from doing it.

Honing a cylinder is mainly done to get rings to seat which helps with compression but more important, controls oil entering the combustion chamber from the crankcase and burning. Honing is more of a 4 stroke thing. Who cares if we burn oil in a two stroke  In small two cycle engines where there is no separate cylinder head, I think I would stay away from honing because the stones won't do a good job at the top edge of the cylinder. I've re-ringed lots of Homelites and just let the rings seat themselves and left the scuff marks in the cylinders. One thing that does need to be check though is that there are no burrs anywhere around the ports. These do need to be buffed back. |
