Thermoquad vs Edelbrock
Might just need a rebuild. Could be Shot needle and seat leaking causing a flooding condition at idle and a shot accel pump for dead stop acceleration.
Either way, it's not too hard to take a carb off and put it on. As long as you keep the old one you aren't hurting the cars value.
Keep in mind the eddy might need a little tuning though to get it right.:thumblef:
