ZOWIE!
Yes, it sounds like you've "done this before"... So I'd say you need to verify the grounds are clean and solid, maybe test voltage supply into the coil? Solid voltage?
HMmmmm CAPS seems okay..

I re-read your original post and am curious why your idle is 900 rpm. Seems very high to me, No I didn't go looking for specs but it does seem high to me. My memory thinks it should be more in the 700 to 750 range. For giggles, if you're curious also.. Set your timing light up and start the motor, let it warm up if needed. Pull the vacuum advance hose and plug it, then watch the timing marks while you lower the idle rpms. I'm curious if the dizzy isn't already moving the mechanical advance weights and changing the timing due to the (perceived) higher rpms... If the timing also changes then either the mech'l advance springs are weak or the dizzy setup might need to be different?Last edited by 34_40; 08-18-2017 at 03:37 PM.
