Hi John

Yep, I'd noticed your fetish for big engines ... that Marine Engine of yours ...  :D

What does it weigh anyway ??

Had a bit of grief with the PTFE power piston. That locked up. Had to skim some .002" off it.
I think I read somewhere that many polymers expand a lot...
It's been running at a fast tickover for some 30 mins. Did not tighten up after that, so I presume it's about right now.
Although it feels a bit loose.

Needs a fair bit of heat to get away, but then it just goes on a sniff of flame.

Anyway, I need to look at the Displacer crankpin bearing. It's that making all the clattering. 5mm bore ballrace on an undersize pin. Knew all about it, but wanted to get the contraption going.
If you look closely, there are several screws missing... might even stick some in.  :D

Big improvement after the other night, went like the clappers for about 90 secs...
Until the hot cap solder let go ..  :(

Have fun

BC
