I bought this saw which as best can be determined was a 266 with a 48mm 162 top end



I bought this 50mm OEM Open port 268 top end




My problem is now that it has a 268 top end the top cover no longer fits since the
cylinder is taller.

I tried a top cover off a 268 and the screws don't line up with the holes in the case.


I'm trying to figure out a solution that would work on making this saw functional
I've got the 268 intake and air filter elbow on and the saw runs but no exactly practical
running it with no top cover.

I may be having a brain fart but that case was shared 262 261 266 correct? 268 and 272 shared another chassis?

Have no experience swapping parts between the two cases but have spares for both it needed...IE 272 top cover or 266 P&C.

Edit: Never mind, went back and read through in better detail.

That is weird

So if you could get the spark plug to clear the cover, it would mount correctly, the cover clears the top of cylinder in other words...

Is there not champion spark plug that is shorter, meaning the distance from the threads to the porcelain?

That was the one thing I didn't check see if I could run a shorter plug.


I'm not super familiar with this series of saws but checking Mike Acres site

The 61, 61 Rancher, 162, 66, 266 SE/XP all use the same crankcase and top cover configuration

If memory serves, the case of that "family" of saws was changed some time in the late 1980s - it isn't really connected to the different models, but to the time the case was made?

Correct. I know for sure the 61 had 2 different orange top covers with 2 different bolt patterns.....the left rear bolt is about 1/4 different between the 2. Im sure they's some variations between the others too since they shared the same cases.

The difference in the crankcases and bolt patterns on the top covers corresponds to the early twin coil saws like the 266, vs. the later single coil saws like the 268/272 and such. The height of the mufflers is also different. A later muffler under an early top cover and they'd be touching. Those early mufflers are NLA from both Husky and Jonny, so be careful if you start modding it. There is a Tecomec aftermarket one out there, but is pretty restrictive compared to the originals.

I like Jimmy's idea about cutting and capping the top, and I do have those Jonsered plug covers. I could bring one up next weekend if you want.

BUT..........I'm guessing that the top end you are using is an aftermarket job, and that's why it's taller than the others. I have some OEM top ends here, 266XP, 268XP, and Jonny 670, and they are all the exact same height.

It's a OEM 50mm Open port 268 top end, the one that was on it was a 48mm closed port cylinder.

The old cylinder is about a 1/4" shorter than the new, and the old cylinder was tapped for a decompression release.

The bottom end appears to be an early 266 two coil model

Bob bring along one of those Jonsered spark plug caps.

Hmmmmmmm now I'm puzzled. Maybe a difference in the combustion chamber would account for that?????

I'll bring the cap.

BTW, Walt ported one of those open port top ends. He messed around with the intake or something, and it came out pretty nice.

Just thought of something else here...........a 48mm closed port jug is not from a 266. That cylinder was used on two saws: the 162SE that preceded the 266SE/XP, and it was used on the Jonsered 630 throughout it's model run.

The cylinder I'm guessing is from a 162 . I'll bring it all along to Walts, the saw operates and functions normally but just
can't get a top cover to fit it unaltered.

I do like the saw as a concept 268 50mm top end on a smaller 266 crankcase it's a lot of
saw in a small package.

Well got my problem solved....


13 # 10 oz fuel of gas and bar oil. 67cc's


I've gotta trim around the muffler a little but should be a neat saw.
The 272 muffler does look a bit goofy.
