Hello,

 

I'm looking at buying a distributor for my new engine and have found one for sale at a reasonable price. The only thing is it doesn't have a vac advance which I need for my road engine.

The dizzy has a blanking plate screwed on where the vac advance unit normally is.

Is it possible to fit a vac advance unit or will there be issues?

 

Cheers

Elliott

but the mechanical advance will be set to suit not having a vac advance.

 

get the right one for your new engine of you will be buying another one.

Have you got a Haynes?

 

It should have info for the various models. Or you put your engine spec on here : A or A+, compression ratio, cam or the engine number if it's unmodified.

 

Getting it right could recoup the cost in fuel.

It's a modified 1275 A series, 10.1:1 compression ration with a 266 cam.

 

The distributor in question is an aldon yellow 45d

That's not far off the Spec of an MG Metro, though the wrong fitting, being A+ not A.
