Installed an 8000 p&c set last week which came from the factory
with a pop up and quad port cylinder. The old flat top p&c ran
a loose squish. The new set after installation is around 180psi
stock with about 15 minutes run time. OEM Part number for the
p&c set is p050005320. This is rings, piston, clips, pin, base
gasket, and top bearing.

i'd also like to know ;) by a "pop up" do you mean a domed
piston? the newer cs800 top ends are what's being supplied, and
they're a domed piston, not a 'pop up'. however i have seen both
domed and flat tops on these saws from factory. the compression
on a newer cs800 is usually around the 160-170psi range. show
some pics. :)

The older 8000 pistons that Im familiar with are 52mm in
diameter with a full circle skirt (not slipper style) using a
13mm pin. The pistons use two 1.2mm rings and have a flat
crown. The cylinder design uses closed transfer ports,
sometimes called tea 'cup style', that breath through the
windows of the piston with one on each side.
The newer parts that I recently installed were different.
The new oem cylinder has a vertical divider cast down through
the center of each transfer duct, with one large opening at the
bottom, but with two openings on each side at the top transfer
port position. The transfer ports continue to be of the closed
style and are fed through the piston windows.
The new oem piston has a .030 flat top 'pop up' in the middle of
the crown. It has been cast this way from the looks of things.
When I take the pics I will look to see if the piston was domed
first before having the pop up machined off flat.
On this engine I measured the old squish to be .040". Standard
static compression for the engine per the manual should be
135-150 psi.
The combustion chambers are small which helps make good power
given the loose squish.
There is a provision for a compression release on the side of
the cylinder but Ive never see one that was installed.
I will get some pics up in a day or so.

WELL! the echo echo is back together, it drank one tank of gas
and is sitting just a hair under 180psi. :) seems to be a bit of
a dog to pull over right now so i might think of tossing a
decomp somewhere out of the way. good torque for the first tank
and she was a little richer than i really wanted. just barely
coming clean in the cut. the new 38" bar and clutch bearing
should be at the dealer today or tomorrow. should have no
problem pulling it 8)
good thing. me and my buddy need to go and clean up a 4' dia.
elm on one of his co-workers backyard after christmas :)
caaaaaaaaaan't wait! :-*

I bet that old one with tighten squish I have is around that.
Hence I run a MS460 rescue handle on it D-ring.
It could use a de-comp too. But I am used to it and my old 066
non decomp was the same.

oh i have no problem starting it :) i just loved the look on
alans' face when he slowly pulled the handle while the saw was
sitting on the bench.
sheeesh! ( i won't repeat the actual word ;)) thats a little
heavy!
feels like starting a husky 2100 :D
drop starts are a b1tch, but no biggie! hoping it won't climb
too much after a few tanks. these saws seem to have sufficient
cooling, and i don't think it would be a hot runner anyway. but
i don't want to be running any of that funny smelling hi octane
fuel i need for the mustang. i like regular fuel, even with the
ethanol ;D :o
yup i've heard you saying you like them rescue handles (or
snowblower handles up here :D). i figure one of them small
rubber mcculloch handles from a mm110 would be a nice fit ;D

well, i had to. ;D just couldn't resist. ;D i opened up the
exhaust on the 800v :)
even gave it some useless 'bling' as the kids say. ;) added a
5/8"idx3/4" long piece of stainless tubing. gutted the exhaust,
added the tubing to the deflector. polished the end and painted
the rest of the deflector. the shinny don't do nuttin for
running, but it makes people look. :D
