Husky 266
By: woodplayer Date: July 18, 2011, 9:13 pm
---------------------------------------------------------
Here are some photos of a 266 I picked up for a cheap price.
(It's nice to have a Stihl dealer that lets me go through is
stash of old saws!) I found the exhaust side of the piston
badly scored and aluminum transferred to the cylinder. The
carb mounting block was defective which was likely the cause of
the lean burn. The cylinder cleaned up really nice and I picked
up a new piston/ring and carb mounting block at ChainsawR.

The saw runs great and has 150psi. I noticed that there appears
to be a grommet/gasket missing from around the throttle link.

As well there is a hole in the cover which I assume could be
open for winter time as it would allow the carb to draw warm
air, however is something missing that would close this hole for
summer time use?

Looking at things, it seems if the hole in the cover was closed,
(and I had a grommet sealing around the throttle linkage) the
carb area would be completely sealed?? Where is the fresh air
entry for the carb?

Good looking saw. I have 2-266 and 4-5 61's same style 2 part
ign. There is a bellows that goes around throttle PN:
503-4450-01. There is a plug that goes in the cyl. cover for
summer PN: 501-6152-01. Any cap/plug that will fit the hole
will work. Never thought about where it get air from but it
does. Will have to check em out.

I had the red version 266, a Jonsered 630. Excellent 8 hr a day
logging saw. I know a few loggers who still cut with 266, 630
and 670's today.
Those saws get their air intake through openings below the carb
between the fuel tank housing. Clean part of the saw in this
area, also less chance of sucking in snow in the winter while
falling.

Thanks Farmboy I found a plug to use in the hole in the cover.
I ended up removing the carb to find the air intake hole
underneath as you suggested HolmenTree. It's pretty small, only
5/16" diameter. I also noticed a plug in the side of the
airbox, any idea what that is for?

I think I'll just use some foam in the throttle hole, that way
there is another source of air plus it would be filtered.
With the 20" bar the saw is front heavy when sitting and the bar
ends up touching the ground. It just has a flat style of dog.
I may try to make a small spiked dog that extends downwards that
would stop the saw from leaning forward when sitting.

I had took in on trade a 266xp partial PHO a few years ago
thinking I could use some parts for another project. I was
wrong and decided to just get rid of it instead of learning
another new to me saw. I had got it running the way it was and
sold it for $30-$40 as it set PHO.
Whats the difference in 266xp and 266se?

Woodplayer the large hole where the throttle linkage goes
through is the primary air intake hole, the small hole may have
been for optional heated handle wiring .
The plug on the side is probably also for heated handle wiring
, I could be wrong. Been years since I had a saw like this.

Not much, except the 266xps are newer, compared to newer 266ses
(after some time in 1985) - but older 266ses had another carb,
and a bit less power and rpm - as far as I know, as did the ol'
166se (1978, US only).

[/quote]As I said there is a boot Husky calls it a bellows that
goes around throttle linkage $4.00. If it is not filled it
allows a lot of dust into carb. area. 61,272,181,281,288,Jred
625-670 all use a bellows to seal carb, area. The small hole in
the center is for a rubber plug PN: 501-5510-01 Seal that
supports the carb. Holman is right on the plug on the right
it's for heated handle wiring. IPL too large to post.

I see the bellows in the 266IPL and 66 IPL, and the plug that
supports the carb is listed as 501-5510-01 in the 66 IPL and as
503-6976-01 in the 266 IPL.
But this still brings me back to my original question, if these
holes are all sealed up, where does that carb get fresh air
from?? ???
