Husky 266
« on: July 18, 2011, 10:13:00 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).

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?? ???
