In a old AS thread, JJ says a 54mm 046BB piston will work in a 2083...... If my piston is scored, (i'm sure that it is) I may try it.

I seen that too. But when I compared the 066 piston it  looked better to use IMO. Thats what is going in one of my 505.

Stihl 066 660    54mm
Piston Pin 12mm x 8mm x 33mm
Pin top to top of Piston 17mm
Height 43mm
   

Stihl 046 460  Big Bore   54mm
Piston Pin 12mm x 7mm x 35mm
Pin to top of Piston 15.5mm
Height 36.5mm


Stihl 066, MS 660
Replaces Part Number 1122 030 2005
Bore 54mm
Rings 54mm x 1.0mm
Height 42.75mm
Head Type Flat
Piston Pin 12mm x 36mm x 7.75mm
Compression/Pin to top of Piston 17.0mm

I think this was the oem 505
top of pin hole to crown 16.75mm
height 42.65mm
pin 12mm



BB7900 specs
Height 40mm
Pin 12mm x 7mm x 32mm
Pin hole top to top of Piston 13.25mm

Another parts site says it is. Husqvarna 503723502 PISTON CPL 54mm

Like I said I would have tried the 066 way before the bb046 just by looking at paper measurements above.

I wonder about the skirt on the 066 though too. I can deal with the squish, but that skirt will change the intake timing.
