Just had a horrible thought how the heck do I set up the vacuum advance now Ive got twin 40 dcoe's or do I just leave the advance tube off and reset the timing or would a later non vacuum dizzy work.

Any help would be appreciated.
Cheers,
Bob

It may be poss to connect all four port runners together to get a constant-ish vacuum. This works on some engines, but on others still gives a nasty pulse effect which will confuse the hell out of the dizzy. The safest bet is to get a non vacuum dizzy, or if you can stretch to it go for a Megajolt set up. Haven't got that far myself, but MANY others on here seem more than pleased with it.

nothing to do with me thought the guy sellin it is ok

Leave it disconnected --- vac advance has zero effect on performance is purely a dodge to allow the running of weaker mixtures at very low loads/throttle opennings to reduce fuel consumption.

in the 60s/70s a common l trick was to remove the vacum capsule and fix a screw through the distributer base plaste to stop it moving.

Thanks for the input guys
