Suggestions for 394xp rebuild
DIR By: Smgchandler

---------------------------------------------------------
I have a 394xp that was run without oil in gas. I have no money
in it and i think everything is there except a bar and chain. I
have not removed cylinder to take a look so it’s possible i may
be able to re ring and clean up cylinder because the saw was
almost new when this happened. Not sure how old the saw is but
it’s been under a bench for several years. My question is since
i can’t find cylinder unless i go with 395 and the mod then what
are my options. Gluing the port onto top of carb just doesn’t
appeal to me especially on a chainsaw. I would be perfectly
happy with stock saw. I cut wood for firewood only but would
really like to get it going again. I’ve read it is a beast I
would probably replace crankshaft seals fuel lines and anything
else you want to suggest. I appreciate any information on
quality parts and would certainly be interested in any parts for
sale that you think i may need. Thanks

The saw is froze. Can't pull rope at all and with muffler off i
can see side of piston has a scar on it. How hard will it be to
get the jug off ? Any suggestions. Saw cosmetically looks
great From experience what do you think cylinder will look
like I don't have time this evening to play with but maybe in
a few days

Pour atf into plug hole. Warm it up good and let it seep. 2 days
if that and it should break the rings free. If that doesn't work
then you might have to pump the top end full of grease by making
a fitting on the spark plug.

Mdavlee that worked. ATF Didn’t take 2 days 😍. Pulled
this evening and it’s loose. I bet it doesn’t have any
compression but at least i can get jug off now. Tomorrow eve i
will see if i can get it off and post some pics of inside
cylinder. I’m not sure what is missing but seems whatever the
air filter sits in and goes onto intake is missing. Maybe some
type of tray that sits on the round intake tube. Anybody know
what this piece looks like or what it’s called and where it can
be had ? Thanks

like to know what the black spacer plastic piece is in sitting
in orange pic It’s brittle and needs replacing What should
i use or how should i begin to clean inside of cylinder I have
a cylinder hone for drill but that may be bad idea if what i
feel is aluminum

Is fugly a word or have some of you fellas seen worse ? I’m
going to remove piston from rod. With new piston does it matter
which way you turn it. Is there an arrow for front or anything
?
