Hi,
just a quick question, I am currently running a 2.0 pinto on twin 40 carbs in a sierra.
i have read that you shouldn't (don't need) use a dizzy with vacuum advance? I have piped mine in but can't get it running right, it idles ok but feels like it's dropping a cyl down the road. Where I have piped vac in is on the back carb.
so do I need to get a dizzy without vac advance on it?
cheers
