Vacuum advance

[NickFerrell]

On my 1978, I noticed that there is no vacuum advance. The car runs fine regardless, I just was curious whether a vacuum advance was stock on all years.

the early years only had the centrifugal advance.

Yup, dual points and centrifugal advance. I think vacuum advance started in 1979

None of the Fiats I've owned had vacuum advance, I don't recall seeing it on any twincams in Oz, must be a Yank thing.

I would think all the cars with electronic ignition would have it (1979-on). I know they had it in Europe, I don't see why they would not have it in AU. It's function is to give better fuel economy, maybe gas down under is cheap?

I don't recall seeing them either in Oz, I had wrecked a 1984 Argenta (late 132) with L-jet fuel injection, it didn't have the vaccum portion (it's on my car now) nor did it have an O2 sensor

Around US$6 per US gallon.

1903 - 1978: Centrifugal advance / mechanical advance / points-type distributor
1979 - 1985.5: Vacuum advance / electronic distributor

Lucky people: have a Marelliplex, which was a FIAT-supplied part sold through distributors to upgrade the mechanical type to electronic. It did not have the vacuum advance. It works on all motor types. They were not rare a few years ago but are now, and people who sell them ask entirely too much for them. Cheaper to get a good vacuum advance carburetor.

If you have a vacuum type distributor on an earlier car, which is a common thing, then you should have a carburetor that has the port of the vacuum advance, and it should be hooked up, and it should work.
