Working on freshening up a Breisch little brother air cooled for a friend who purchased it and here is what I found when I took the piston out. Since then I bought 3/4” rings and plan to remake the piston. The owner has the prints and says they do not have rings shown on the piston...weird... Did they really spec it out without rings?

Just 3 oil grooves on the drawing with no rings.

Hi from British Columbia Canada...
Would you be interested in contacting me to discuss my upcoming build of the Lil Brother air cooled?
Much appreciated...Carson

Don’t know how much I can tell you as I do not have the plans, just the completed engine. But it appears fairly straightforward. Lots of tiny parts though...but ask away.

I also have a Lil Brother air cooled. I can confirm that the Lil' Brother has three 1/16" wide grooves on it and no rings.

If you're going to use rings make sure the bore is exactly .750 or the compression won't be good at all.
