Timing, carb, and cooling trouble

So I finally got the dart running. My Carb spits fuel up at me with the air cleaner off., I can not seem to get her below 10 degrees tdc.I cant turn the dizzy any farther. The mark on my balancer may not be right,or i am a tooth off when i set the dizzy in. When I put the light on her she seems the smoothest around 15 advanced. And that is not smooth at all. She will not idle on her own any where. My Carter I just rebuilt, and it spits fuel out sometimes when i rev her up.. I just put in a thermostat, spring to head the other day ,and it opened at 180 degrees like it should. She didnt over heat but got above the half way on the gauge. Ive never driven my 63 gt. She did not run when I bought her, so i do not know what normal is for her. Also the rear tires turn while shes in neutral. Any ideas why? Thanks .
