So after 136 miles, I filled up.. I've gone from 11.99MPG to 22.82MPG by replacing the bad mechanical advance! Now we're getting somewhere. Every bit of those miles is city driving! Here in a little while I will swap from the 20W-50 to the 5W-30 and see if that's worth anything. I need to replace my exhaust first.

Thanks for the help folks!
