Okay, I am finally getting back to getting this running again. I had to order the prechamber seals from the local dealer. I brought one of the old ones with me since there are different sizes. They ordered the standard 2mm for me. Do they compress? Should I worry that maybe I should have gotten the 2.3mm? The new ones are the same thickness as the used ones.

Rusty, the engine number I have is 616 10 312539, and the prechamber part number was 616 010 01 52, so it looks like I have the right prechambers.

I went to install them but can't find what the torque should be on the lock rings. Anyone know?

I have attached pictures of the old and new prechambers. At first I was kind of worried that maybe the piston would be damaged, but after I thought about it, I figured the pieces had to be pretty small to get through the holes in the prechamber.
