Car won't run

Recommended Posts

Folks,

 

looking for for a little help. My stock '76 2002 was running fine last year, but now will start but won't run. I have installed a new BMW fuel pump, and changed the lines from the firewall to the carb. If I pour some gas into the carb it runs and then stalls out. If I put my hand over the carb throat I feel suction, and it will start but as soon as I move my hand it dies. Carb is the stock '76  Solex. There is gas in the tank, I will check the fuel pick-up screen in the tank this weekend. Could the float be stuck or a jet clogged?

 

Any helps suggestions or tips please send my way, I won't to get her back on the road for summer.

 

thanks,

 

kris

Check the short length of fuel line back by the gas tank--the one that connects the pickup unit to the plastic fuel line.  If it's the original cloth-covered line, replace it with US-style rubber fuel line.  The cloth covering on the OEM lines will cover cracks in the rubber hose beneath; a mechanical fuel pump would much rather suck air than gas, so the smallest air leak on the upstream side of the pump will cause it to suck mostly air, not gas.  

 

And of course you did check to see if you have spark--a nice, fat blue one, not a little wimpy yellow one--at the plugs...

Check that the coming and going fuel lines are correct at the pump. Then detach the fuel line at the carb, put it in a bottle and start. Then you know for sure if you're getting fuel or not.

If not - one thing to check is that is the length of the fuel pump actuating rod correct for the pump. There has been different length rods, different thickness bakelite spacers and different kind of pumps.

Three basic things are needed for any four-cycle engine to run - spark, fuel, compression. I would check for spark first and look at the condition of the points too. You could have a weak spark but badly oxidized points that are preventing it from running. Do you have a compression gauge? An experienced ear can usually tell if it's got at least some compression. With no compression it will sound like a sewing machine will cranking it over. Of course, since you said it starts, but won't keep running it's probably not the compression. Key word = probably. Personally, I'd take the top of the carb off and have a look-see inside. You could also remove the plugs and see what they look like. If they are bone dry, it's probably not getting gas. Soaking wet = flooded.

    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
