Best Book Or Online Resource To Learn About Solex Carbs


Recommended Posts

Hi folks,


Trying to increase my knowledge here.  I have a 76 with the original Solex carb.  Are there any books you folks recommend to learn about carbs in general and/or specifically about the Solex?  I've found a few that cover Webers but not Solex

Coupla thoughts...


Just in case you don't know (and I'm sure you do!) those Solexes are fraught with problems--especially the choke assembly and the vacuum diaphragm that opens the second barrel).  Most folks think the best solution to the OEM 2 barrel Solexes is to toss it CD's neighbor's pool and install a Weber in its stead.  However, not all Solexes are a PITA--the 1 bbl's used on pre '72 2002s are bulletproof, and other older Solexes without all the emissions stuff but with mechanical secondaries and manual chokes are also very good carbs.  I've been looking for one from a mid 60s' M-B 220 that fits this description; want to try it on my '02. 


That being said--there's a good book called "Tuning the Solex Carburetor" that was published by the S.H. Arnolt Corp back in the early 60s that really goes into a lot of detail on the subject, including how to calculate jet sizes based on  engine displacement, compression ratio etc.  The trick is gonna be finding one--but perhaps someone has scanned it and put it on a disk or web site.  It's the best book I've seen on Solexes...

    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
