Dellorto Dhla 45 Floods


Recommended Posts

I have a problem with my carbs, they flood; fuel drips out of the horns.


Tested fuel pressure, it is 2,5 psi(adjustable, but set at 2,5, so it´s not the problem). If i hold the floats in top position, they don´t let any fuel through. The floats are not leaking, submerged them in a cup of water, no bubbles.They are plastic. When i put them back on, I think they flood, so the fuel drips out of the horns.What can I do?

No matter how much I adjust, they still leak. I suspect there is something off with the floats, because I can´t get them to 12 mm without bending the float tabs. Anyways, I tried to adjust and bend as much as I could to make them close as early as possible, I had maybe 15-16 mm clearing between the top and floats. Still leaking. 


When I tested one of the carbs, for maybe 20 seconds, measuring the fuel presure on the other(only one carb getting fuel) it did not leak. Adjusted the other one like the first, tested, and both were leaking.

    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
