Chainsaw Repair

I've tried 3 makes.   The two that are currently readily available were so bad I considered them un-salvageable.   There is one that I tested and is pretty good.  With a ring upgrade it would be fine.  However it isn't finished and out there for sale yet.

One of the 'bad' kits was so poorly made the insides of the transfer ports were never finished, yes they were completely closed, and had to be drilled and ground out.  In that same kit the piston also wouldn't go through bottom center without grinding the bottom of the piston skirt to clear the crank.
