Lately, I have had problems with my '76 non-tii engine. It fires up nicely and after the temp gauge gets around 3 o'clock position (10 minutes here in the frigid north), it will stall out. Starting it again is nearly impossible. This has happened on the road which can be frustrating. The car will be going into storage in a couple weeks so I do not want to spend a bunch of money on a tune-up, just to have it sit in storage for the winter. Since it starts fine and runs great until it's warmed I am thinking it's carb-related. It has a Weber 32/36 DGAV carb upgrade (common, I know) on it. I have sprayed carb cleaner in and around it and cleaned linkages with a toothbrush, but this has not helped. I think I will be taking it in to a shop soon. I just want to have some idea of what it could be before I go in. Also, I just want a quick fix to last me the one hour drive to get it to my parents barn for winter storage. I will deal with new plugs, points, rotor, condensor next spring.

Any suggestions would be greatly appreciated.

carburetor icing. This was nearly always when the weather was between feezing and 40 degrees.

Use a bottle of dri-gas with the next fillup, and see if that cures it.

Sounds like the choke is stuck closed. I don;t know that carb but.... You might try taking the filter off when the problem occurrs and looking down into the carb for a plate that is blocking the air flow. try lightly tapping it to see if you can get it unstuck. This plate is to restict air flow when the motor is cold as the percent of air to fuel to make the car run is different than when the car is warm. For some reason your is not opening after warm up as it should.

then it's getting too much fuel(not enough air) and flooding? Which would make it difficult to start again. Once it sits for a while (and dries out) it will start again. Sounds reasonable.

Any suggestions on how to get the plate not to stick? I cleaned/wiped with carb cleaner, but the problem persists.

Any Wisconsin gas station should have some in the Fall and Winter months.

I'm not familiar with the brand names anymore. Since I have a tii, and all my other cars had FI, I haven't needed it in a while.

It acts like antifreeze for gasoline...keeps it from freezing.

Are you using a stock air cleaner and warm-up airbox?

Good Luck!

I'll try to post pics later. Not sure about the icing up, though. The car sits in my attached garage so the temp isn't too bad, yet.

once the engine is warm try tapping on it with our fingers to shake it loose maybe? I am not so familiar with this carb so I dunno. If you can identify the plate (should be just inside the barrells of the carb) then by looking at the linkage you may find something getting stuck. Often these linkages have a stepped cam that sits against a screw. That is the high idle speed screw. This stepped linkage should swing out of the way and not come into contact with the screw thus allowing the choke to open.

Is it rainy and damp?

If it stalls and won't start immediately, but after 10 minutes, restarts, it might be icing.

It may also be starvation from a fuel pickup problem, either in the tank, a clogged fuel filter or weak fuel pump. Look in the trunk for a pinched fuel or vent line, too.

How do you check for a weak fuel pump?

I will go through the fuel system (tank to carb) and check for clogged filters, kinked lines, etc. As well as putting in some Dri-gas. Problem is I cannot run the car long enough to get the old fuel out of the system.

...with me. It was good insurance. Easy to replace roadside, if necessary.

If you've never replaced yours, it might even be the factory original. Now might be a good time.

    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
