Enya 60XF-II ...?
I believe this is the Enya model 7101 60XF-II Can anyone make a positive identification? I know there were several different variations of the 7101. This one didn't come with the box but it doesn't look like its ever been run. It's a ringed engine. Is there any way to identify it without removing the front housing? I have new gaskets but if I don't have to needlessly disassemble it I'd rather not.

I'm guessing it's a II because mine has a III stamped on the edge of the LH mount. I'm a bit hazy on internal changes but the original 60X had a 15mm crankshaft and a different front end casting.
As an experiment, I raised the compression on my 60 to 13.5:1 and it then had exactly the same power as my son's 80X using FAI fuel. Quite a decent improvement
