Thanks for the diagramme, Postie, and your comments, Alvin.
The only problem with drifting out the sear spring, is trying to get it back in for reassembly! That mainspring is one stiff critter. It would put Viagra to shame
.
Was there a tool....something fork-shaped......that would insert between the mainspring "cap" and rocker, so that by applying rearward pressure, the rocker would slip away?
Still thinking about that.
As for solvent, perhaps pure mineral spirits to remove the dried gummy residue, then Hoppes "Blast and Clean" for good measure, prior to oiling. I still like Rust Check, or G96.....but do I need a lubricant with higher viscosity?
I'll post some pics soon. Thanks for yours, Alvin.
Cheers,
Bill
