Hi Ken:

Many years ago Vic Jackson of L.A. taught many of us to take of the action
stack, go down the line flipping out each repetition spring to one side,
then using a carpenter's pencil and cloth clean out the green goop. 
This is done most easily with the action upside down on the work bench.
Then, with the same pencil lubricate the slot. The rep springs will be much
more consistent but will seem stiffer, so regulation is definitely in order.

PS Vic also lubricated the groove with VJ lube which he invented.
