.....Or maybe somebody had no idea what the hell they were doing.

Picked up this 042 as a parts saw. Noticed it was modified with such features as a Tilly HS minus the choke shaft and also partially bored out, huge exhaust port, gutted muffler, no air filter. It was starting to look like a hillbilly special. After getting the muffler off, I saw it was missing the lower piston ring which would explain the low compression and all the spit-back fuel in the air box.

So, I started thinking maybe I could save this saw. Might be neat to have. Removed the cylinder. My first clue that something was amiss was the piston seemed to be hanging up as I was sliding it out of the cylinder. Get the cylinder loose and I find this port job.

Extra ports or whatever carved into the cylinder walls. The cylinder was decked and the piston was hitting even thought I see somebody attempted to knock down the crown. Little too much metal hogged out of the intake. JB weld couldn't help this catastrophe. Orange silicon for a base gasket. Then, all the mistakes were compounded by running without an air filter.

This saw will remain a donor saw, but will NOT be donating a piston or cylinder. It does have a good ignition/flywheel, recoil, clutch, chain brake, modded carb, trigger stuff. Plus, the bottom end feels nice and tight. Should be enough for my 048.

OK, so what is wrong with it?

Us hillbillies use blue silicon, so it must be a michigan hotsaw..............
They take out one ring to mimic a Husqvarna........
But I digress......................
 
This is why you don't let your pet monkey play with your die grinder and your favorite chainsaw.

Morbid curiosity...............did it run?
 
It's only hillbilly because it didn't make big power. I've seen some porting that looked like real crap but was actually the cat's a$$.
 
no, thats what you call a monkey job. the pet monkey did the job with a die grinder, and made a mess of it.

I have to wonder if it actually ran like that. the way I figure it, the ports run a high risk of snagging a ring, and screwing something up, not like that cylinder is in great shape anyhow, I can see what looks like gouges and chips in the nikasil lining there.
