Dizzy...
Hi chaps,
I need some help, i am using a 1600 pinto running 40 webbers. Which dizzy should i use? I cant run the vacumn advance with the 40s,so is there any way
to set the advance to give the right amount through the rev range??Or do i need to fork out on an expensive replacement?
Thanks
Steve

When the throttle is flat to the floor you get little or no vac advance anyway. Vac advance is essentially an economy device to allow weaker mixtures
at light throttle openings.

i was wondering about this recently, so apologies for borrowing the thread!
is the source of the vacuum the airbox or the carb? obviously the vacuum is created by the engine sucking air in, but my distributor has a vacuum pipe
going to the underside of the carb. So i was confused as to whether or not i had to have a vacuum pipe to the carb, like the original one had.
any ideas?

The vacum is (mainly) caused by the restriction of the throttle the tapping point is usually just downstream of the throttle this why at full
throttle the vac advance plays little or no part when the throttle is wide open.
Some vacum advance ports are on the carb in a postion where they are covered over when the throttle is completely closed to give smoother idling
others are jusrt straight on to the manifold.

I was also wondering about this as i have a 32dft carb with no take off point, and could not decide wether to tap directly into the manifold where the
servo originally connected, or leave it disconnected.
