Distrubutor

[Del1968]

Why does the distrubutor need the vacuum advance on it connected to the carb and does it matter if the one I have ordered from demon tweeks ain't got it or I should say the one they have sent me ain't got it

[theduck]

It has its benefits but it isn't essential.

[Bob Tucker]

It provides more advance when you are cruising on a light throttle to aid economy.

I think!!!!

[Del1968]

So will it matter that the one demon tweeks is sending me ain't got the vacuum on and what do I do about the vacuum hose off the carb do I cap it off some how

[Bob Tucker]

It doesnt matter that you have no vac. advance.

You do need to cap off the tube leading into the manifold/carb.

Cool cheers for that bob saves me sending it back its going in on Thursday to get carb serviced and tuned up so might get them to put new distrubutor on and do timing

[Guest lotusPaul]

If your dizzy is not a vacuum advance it will be a mechanical advance dizzy..bobs n springs type stuff. So you just need to block the manifold take off, or you will be sucking in air and leaning the mixture.not good.

You will need to ensure the mechanical advance curve is suitable for your application tho.

Standard Pinto dizzys use mechanical advance as well as the vac advance

[Del1968]

Think it's the standard distrubutor with electronic ignition so it can't cope with the ignition curve when you have a different cam fitted the distrubutor I am getting is an aldon distrubutor with with the electronic ignitor

[Guest 2b cruising]

Don't electronic types do there own timing adjustments.

[Guest lotusPaul]

Not on a dizzy. The Aldon ignitor is a cracking but of kit, I had the ignitor 2 with matching coil on my lotus twincam before going EFI. The only thing it adjust is the dwell time to create a bigger spark under certain conditions.like start up and hard throttle openings. The actual spark timing is set as it would be.

To clarify, Burtons should supply the Aldon with a suitable mechanical advance curve for your pinto and no vacuum mechanism. The electronics are all contained inside the dizzy.

Ford electronic dizzys are of at least three types, have external electronic units (ESC, ESC2, TFI) and have vacuum advances either on the dizzy or in the external electronic box.

All dizzys need to be fitted in the right rotational position to set the base spark timing which the mechanics or electronics then modify when running according to engine speed and load.
