Hmmm. I was under the impression that they were, as Tinman mentioned that in his 590 video. Do I stand corrected? I can take that.Not the same jug and piston.

They are in fact not the same jug and piston. Separate part numbers. I believe the port work is different on the two. 620 piston has 2 rings. For more info, I'd look into DynoJoe's vids on YT.Hmmm.

Hmmmmm, I thought my 590 was 2 ring..maybe not..I haven't looked in there in a good long while. It's about a 2013 model or so.
