Hi all

I'm thinking of fitting a megajoltlightjunior to my pinto, i have twin 45's and have been told some have vac signal ports allready. Are these where I've arrowed?

I think thats the starter air jet.

Hi Dusty

Thanks for the reply, Whats a starter air jet? I've got the speedpro book on webers, but it doesn't show these screws

I know nothing but..... for a mapped ignition kit wouldn't you want manifold vacuum signal? I know the rubber pipe that traditionally goes to distributors is NOT manifold vacuum it's some other much smaller vacuum, (main venturi?)
For manifold vacuum, just drill & tap into the manifold somewhere convenient!
I have the opposite problem right now with my V8... the disty expects the "some other vacuum" to be fed in on a pipe & the weber 44IDF just don't supply it..... unless someone knows different???
here's a snap of a home made manifold for one bank.

PS if this constitutes a thread hijack I apologise, I reckon it's a little bit relevant...
