70 duster: updating, and a no-dough pro-touring makeover

Readjusting the timing fixed a lot of drivability issues.

Tach signal rock steady.

Pinion angle change cured vibrations.

The duster is BACK!

Put about 10 miles on it last night. Runs better than it did with a pro tuned carb already, and i know theres a LOT of tuning left to do.
