Right, at the moment my car is close to being back on the road but i have timing issues. At the moment i have twin carbs on a BMW ti inlet manifold and a vacuum advance distributor (which could be crap and need overhauling, when it was on my 1602 a lot of the problems we put down to timing and it is from a '75 which from what i have picked up is not a good thing for a distributor) which the vacuum bit isn't connected to anything.

I do have another vacuum advance distributor from a '73 2002 touring.

What do i do:

-buy a tii mechanical advance distributor at quite a high cost, probably too much?

-spend some time plumbing in one of my vacuum advance distributors?

-if so which one?

-or do i convert to pertronixs electrical ignition*?

Will

*small question about pertronix on a vacuum advance distributor; do you need to have the diaphragm connected up if you have removed the points and replaced it with a petronix kit? does it still use the vacuum advance? if so how?

That wasn't a small question i know i am sorry, it wasn't even a series of small questions saying it just softened the blow.

For sidedrafts you need a mechanical advance dizzy. Otherwise if you plumb a vac line to one of the cylinders it gets full vacuum and advances too quick - crap running.

Also a Pertronix only replaces the points, it does not change the advancing mechanism, regardless of whether it’s a mechanical or vacuum dizzy.

A board member may be able to help out with a mech dizzy.

Good luck, Beaner7102

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
