I know it's getting fuel Bill which would indicate the spring works.  Based on your observation of your spring; which, matches mine of my spring, I'll leave it for now.  It probably won't be until Saturday before I can source an O-ring.  As always, thanks for your support.

Getting a little closer. 

Switched to pump gas at 50:1.
Ditched the drill as a starter  I have a printer motor hooked up to a pc power supply.  I can now hear what is going on. 

It seamed to have a little life in the form of some weak muffled pops here and there.  Nothing significant, but something.

I'm going to try it tomorrow one more time.  If it doesn't run then, I will add an O-ring.

I know I need a 3/8 od O-ring.  I would guess Viton would be the preferred material.  What is a good cross section diameter?  Can I buy them at an auto parts store?

I just used a 1/16 X 3/8 o-ring from my junk box.
