Endlessly Stalling


Recommended Posts

Hey all, my name is Lauren.

I have a 1974 bmw 2002a. One of the first automatics. She's a bit rusty and worn down but usually runs really great The only recent modification that I have done is a body switch (to another 1974 model 2002a to keep the rust at bay) and a carburetor rebuild. Speedometer, and odometer are currently broken, I do not know how many miles, but many.

My current problem is that she keeps stalling when decelerating or stopping. You can feel at high speeds that the power kind of slips while accelerating. So far the alternator, points and carburetor have been checked out, cleaned and pronounced good. The only current thing that is wrong, that I can tell, is that the battery mount is rusting and failing, such that the battery is now at an angle, shifting away from the engine.


She starts up fine after stalling. I tried resetting the idle, and while high idling helps prevent the stalling it never seems to be enough. Any ideas?


Thanks a lot for your input.

Typically, a car that won't idle is caused by a clogged idle jet in the carb.  Take the jet out, blow through it to make sure it's clear and see what happens.

Strap your battery down.  It's dangerous.  The positive terminal may be touching the body causing a short, which can cause an intermittent electrical failure, thus the stalling.  It can also cause a fire.  I would tend to this issue immediately.

Check your timing with a timing light, is all of your smog equipment still intact? if so what distributor are you running and how do you have it configured? ie. are there any vacuum hoses connected and what are they connected to? the 74 has a vacuum retard as opposed to a vacuum advance and if it is hooked up to standard manifold vacuum it will not run well.

I had this happen after rebuilding my carb and it turned out I had cracked the spacer plate when reinstalling the carb. This caused a vacuum leak and effected power and would stall as soon as I let off the gas. I limped her home by engaging the choke; you might see if the choke keeps yours running and if so you';d know it was a vacuum leak.

Yes, there WAS skin on my knuckles before I started the repair...

You don't say what carb-

but some Webers and the Solex (I think) have an electric solenoid that

shuts off the idle jet. 


If that gets unplugged, or dies, well, you can figure out what happens!

    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
