I didnt find any of my old kits. Must have gave then away with
some 084 stuff somewhere along the way.

thanks I'll try them. and I think 60 to 75 for a good carb is
reasonable, by the way

Just a quick thought the carb has 3 screws? One for H, one for
L, and the idle. It seems as if it's not adjustable you're
adjusting the idle in to 0 turns when it should be out some.

I've played with the two needles,the low doesn't do anything to
help, and if I openthe high more than 0 turns, it runs way too
rich at high speed. We had 16" of wet heavy snow on saturday,
and I spend all day sunday cutting up some 30" oaks that fell on
my property. The saw runs ok at speed, but you have to go from
cut to cut, or it will stall. That's a little tough on the arms
and back, as I ran 3 tanks of fuel thru it. Right now, I'll
wait for my carb kit, and let you know what if anything it does
to help.

I just wanted to make sure it was an adjustable carb. I would
try to run the idle screw in a little more.

Run the idle screw all the way in, then hold the trigger where
it idles nice then look at the gap between the linkage and the
idle stop/screw. I've had to "shim" some idle screws to allow
enough adjustment to idle well...

You guys jogged my memory loose with your idle screw talk. I do
remember one of the 084 carbs with electrical tape or something
like that on the idle screw making it thicker to make the idle
work right.

I'll try to shim the idle adjustment screw, maybe that's the
problem. I'm still without power fromthe snow storm, so it'll be
a couple of days more. While I'm waiting, what's the most
obvious cause of bar oil leaking out from beneath the bar nuts
area, when the saw is sitting after running, quite a lot, maybe
a slick the size of a dinner plate? For a saw that's been a
pain in the butt lately, it still cuts like crazy. went from
that to my Husky 272, and the 272 felt like a toy

I tried to shim the idle screw, but it didn't work. It raised
the idle, but unless you keep it about 1/3 throttle or greater,
it will run for 4 or 5 seconds, start to lean out and die.

Well the tillotson kit came yesterday, and I installed it on the
carb. Unfortunately no change, still runs for a few seconds at
low speed then dies. runs good at high speed. I removed the
vent cap, thinking that might be a problem, no change. I added
the paper gasket that came with the carb kit between the carb
and carb mounting surface, figuring maybe I was getting a leak
here, but no change. I guess my next try will be changing the
pulse line, possibly a leak here? I'm running out of ideas,
anybody got any? I ordered another oil pick up tube, as that
was leaking also, but as far as the idle goes, I've got nothing!
thanks
Mike
