Front Servo Question

pilfer it along with the springs

I vaguely remember the Munroe book or maybe it was the TF2 instructions saying to keep the soft inner spring and toss the stiff one. I'll have to look them up.

What does not having that bleed hole do anyway? I'm assuming it makes it act more 'solid'? But how does that make the transmission act in the real world?

Edit- I should add that I've only got the 2.9 band lever. I'd change it, but I really don't want to drop the transmission. I need to get this thing back on the road.
