Great pics Mark, I find it very interesting different engine designs this seems to be a clamshell design.. What do you use to seal the clamshell cases? I find ThreeBond works great and around the seals as well you don't want an air leak past the outer part of the seal.. Some use say a loctite bearing retaining compound to stop the bearings spinning in the case halves as clamshell clamping force is not that great some say, I have never used it yet but I have seen a few spun bearings in clamshell engines...Cheers Chris
