I know I had set the stock one Roger has at 12.8K sort of fat in my area Ohio.  It could have went higher rpm but not to my liking as I felt any higher was to lean.

Weird 12.2K out your way. Air etc?

Yes I think it is the altitude here.    The saws just do not make as much power.
PP 505, 475, 445.

Got my 5020 back together with a new p&c, tuned it by ear then put the tach on it and it was turning 12862, I will leave it there for now till I get some time on it.

There's nothing wrong with 12862 if you just leave it there?

Bird Dog and I were doing timed cuts in a cant with a ported 066. I went from 12,000 and eventually to 14500 in steps.

 The times through the cant were all the same.

Yes, those were free running rpms.

The rpm in the cut remained the same

I also put the .325 sprocket & 16" bar and chain on it and went out to the log, I noted a lack of performance & some smoke & heat from behind the clutch cover, I took the cover off & found the clutch drum & brake band were somewhat blued but no evidence that the brake was on. I put it back together,made sure chain was turning freely and brake was off, went to the log and got the same result, smoke & heat.
  The brake was not on and chain turned freely, took it apart again, more blue on drum & band.
 I put the 3/8 & .325 drums side by side and could see the .325 drum is much thinner metal.
 My conclusion is the clutch shoes are pushing hard enough on the drum rim to expand it out to the brake band.

Curious @old guy what drum did you end up using for the .325 rim set up?  The echo clutch drum I used for 325 rim worked fine.

Got the box in my hand here, Oregon brand Part#513442  type A, designed to fit the following saws- john deere 45 45ev, echo C6400  CS440  CS3900  Dolmer 102
  I put this on my other saw last year and don't remember a problem, but I had a bad chain on that saw and only made a couple of cuts.
 I was looking forword to working with this cus it handles so much better with the shorter bar. :(
