So I worked on a quartet of Grail saws yesterday - the elusive Jonsereds 111. Took me forever to find my first one and then ended up finding a few more in short order.

Anyway, one was a dump find from Canada. Con rod came apart at the small end; not sure what can be saved, but it will be a long term project. In the meantime, it donated the clutch cover, top cover, full wrap, muffler, and rear handle to saws that needed it, so now I have 3 complete ones and one that needs everything.

I posted in the Jonsereds sticky as well and someone mentioned that a Dolmar 166 piston works in a 111/111S. Has anyone else heard of this? Maybe our resident 166 hoarder - @leeha - Uncle Lee, you know anything about this?

Those are really nice looking saws

Scott, It is new to me as well as for using a 166 in a 111S. Another member pm'ed me
about a 166 piston stating you can get more power out of the saw using a 166 piston.
I have both so when I get some time I will compare the two.

Thanks, Lee. Looking forward to details after you've had a chance to compare.

Not everyday you see 4 of those all together.
 
Very nice group of Jonsereds Scott- was it ever determined if the one at the lower left is a 110?

Not yet, but today I ran across a photo of a 110 sitting next to an early 111 with the 1 piece cover. Sure do look a lot alike. Trying to get more details on the 110 -- serial number, any noticeable differences, etc.

Here are some piston dimensions. 166 versus 111S

Diameter 166 55.88 111S 55.89
Pin Diameter both 14mm
total hight 166 49.50 111S 50.08
top of pin bore
to crown 166 17.50 111S 16.62 not counting crown
The 166 is a flat top, 111S is a domed piston
Put the pin through both pistons and the 166 is close to the top off
the 111S piston but the edge of the 166 is taller than the 111S so
it would make more compression providing there is room in the squish
band on the cylinder or have it machined.
I would say the 166 piston in a 111S would make more power.

One of mine is going to come apart.

I was told 166 was stronger than the 111S piston and you could go farther with your porting with the 166 piston.
Maybe I got it wrong and the port job would be stronger.
 
Think a Dolmar CT115 piston would work as well, and also has a dome. Of course, CT115 parts are probably harder to find than 111 or 166 parts, so that may not be helpful.

166 on the left. CT on the right (new piston with dome).
