Ran the brass gasket today and it seems to hold up fine. Got consistent runs at about 9500 rpm on a graupner 6x3, and runtimes of about 2 minutes. When fully warmed, up the compression screw can be backed out and it actually looses contact with the counter piston, may have to shave off a bit more from that one.

The case seems to wear quite a lot, it is already quite sloppy but I guess it is time to get this one into the air...
