I've got a 365 cylinder on the bench. Going to finish grinding
on it and then put it on the 365 case. Then maybe tear into the
2165 and see if there's something there that's just easily
spotted. It hasn't made a cut yet. I don't know if the coil
slipped or what. It will fire up but not stay running and not
make rpm.

Cut4fun had a 272 about a month back that reacted like your
2165. It showed decent compression but didn't run right on top
end. It sort of like it wouldn't come out of four stroking? I
had made a cut or two with the saw a few years ago and it run
just like my 372's. He said it seemed as though the ring was
fluttering when you gave it full throttle.
Bottom line is a new ring fixed it!
I happen to visit his shop after the fact and looked at the
ring. At the position of the transfer on the PTO side there was
severe rounding of the ring on the top side. There was
noticeable rounding of the ring on the starter side transfer and
at the exhaust. Then it was mentioned that the saw was a 268
with a after market 272 cylinder. The saw was back together and
gone but I would have to assume that the ports in the cylinder
were not beveled correctly, and in particular, the PTO side
transfer. To look closely at this ring, besides the rounding at
the PTO transfer, the ring was thinner at this position. The saw
had been in firewood duty for some three years before it started
running poorly.
Ten years ago, I repaired a model airplane engine that had been
fitted with the polymid (Plastic Cage) main bearings. Both
bearings had lost their cages which naturally went up through
the engine. It didn't hurt the chromed cylinder but the ring's
edges were rounded off. I replaced the bearings and the ring.
The morel to this story is - Look at the ring's seating area
against the cylinder. The edges must be crisp and sharp. Unless
of course, you have already put a new ring in it?

I'll look at it. It's apart using the bottom end for timing
numbers. I have another tank on the way to put #3 together
ported I hope on Monday or Tuesday. I want to keep one stock
together.

Finished up a Stihl 290/009 and a 200t. 290 need new crank
seals,rings and some carb work. Also trued up the engine pan and
cylinder. 200t and 009 need some carb work. All are running and
tuned. Also had to fix a leaky 660 oil pump and replace a fuel
tank on another 660. Still waiting on my heating element for my
heated handle 660.

The 660 sounds like it will be great with the heated handle. I
have never used one before and really do not know how well the
work.
I worked on a MS362 and a MS460 today. They both run good but
have been beat up pretty good. Going to the Stihl dealer
tomorrow for parts.

The heated handles on my 266 get warm enough that on a 40 degree
day you need gloves to turn them on.
I have a 371/365 on my bench. Ported it last night. Going to run
it today. I threw my muffler on it so I could test it and I'll
get on modding his today sometime.

I have a Dolmar 6800 with heated handles. They don't get hot
enough to burn your hands but they do get warm if you turn them
on.

The bench is covered in junk from several emergency repair
projects (cars, trucks and tractors that broke). And I wasn't
going to do a chainsaw project this winter - but I'm bored.
There's a decent 42cc Poulan engine on the shelf, and I just
ordered a good carcass with a blown engine. So it looks like
I'm going to clear off the bench and come up with something else
strange to do to a plastic Poulan for entertainment.
