Quoted from Richard_BoK:

I would take the plunger out of the coil, and place a rubber ring (5/16") on the plunger (near the end), so the plunger has less stroke.
I wouldn't do any electrical modifications for this.

I really like this idea. On my Fathom, when the ball eject saucer in the back kicks out the ball, it usually bounces off a post and right back into the saucer, which ends your multiball and really stinks. I took the rubber off the post it bounces off of, but I like your idea better!

Quoted from LTG:

The plunger riding higher in the coil will get a stronger whack.

I don't want to question the masters, but that just doesn't make sense to me. I think the opposite is true.

If you took an extreme example and rigged up an extra fat coil stop to reduce the stroke to be just a quarter inch or so, you'd get a pathetic little bump, right?

Quoted from jwo825:

I think he means placing the ring here

Ah yes, that sounds legit in my book. I didn't realize we were talking about a VUK.

When you say factory coil specs...where do I find those?

Quoted from phishrace:

Google pinball coil resistance chart, if needed.
