got everything hooked up fine.. me and my brother worked on it from 3:30 to 10pm, on thursday. thats with a 1 hour break for friends and dinner

. then for an hour or two we worked on trying to tune the carb, we are still stuck trying to tune it...
my car will run, just not real well, we havent yet gotten it to idle correctly, and all settings it will backfire through the carb.... the timing is fine, everything ignition related is just fine, unless u guys can think of something else.
when i get the carb tuned correctly (holley 600cfm vacuum secondaries, electric choke) i think im gunna blow up my mufflers

because its just flowing more than these 2 inch pipes can stand... no prob cause im gunna order headers soon then get a new exhaust system.
by the way, i dont think my choke is working at all....... it wont move by itself, and its hooked up and everything.... we really need help tuning all the carburator, but theres only so much that u guys can do typing online. thanks for your input!
