Brett - I wasn't dismissing your advice, far from it, and McCoy QC noted.
It just occurred to me that many posts have remarked on loose McCoys running ok (w/o particulars) and I was expecting more "ok".
(Glad it's not a Cub .29 OK!)
More running is definitely in it's future; I enjoy that anyhoo.
(And I wasn't trying to hide from you on SSW - I know you're there too
; some posters there don't post here. )
I confess, Andrew, I don't know how this piston has survived my ministrations.
I'd likely be excommunicated if any of you saw me "tapping" on it.
With a 12 oz hammer.
Did disappointingly little good though.
