I had a cable setup that SUCKED .... Hoa got it from TEP for something like $100, made up of around $10 in bike parts... Hell bike parts would have been even better quality. IF it IS a cable, then try shortening it, lubricating it, or replacing it with some of that high-tek teflon-lined stuff you can get at any bike shop. If it is the rod setup, id take it all apart and find out where it is binding up. the throttles should SNAP shut... its SCARY when they dont!!

It has started doing the fast idle thing where the throttle plates don't close entirely and my idle jumps to ~3500. Should I just count on replacing the return spring with something heavier and live with a stiff accelerator pedal?

Nothing is hanging up at the pedal box and that funky little spring on the outside of the pedal box on the accelerator linkage is even there too. Pulling up on the accel linkage moves the idle back to where it should be.

Ideas anyone???

Thanks!

throttle wobble around and sometimes it doesn't fell like closing. Sometimes idles less than a thousand, sometimes two. It goes a little better than the old one but it is way too rich, just the standard jetting still.

Sometimes the rod linkages will rub against the heater hose causing it to stick like that. NOt trying to be insulting here just thinking of all the things that could cause that. The pivot in the firewall sticking?

Also I have seen them stick when the nut on the throttle shaft is too tight where the linkage attaches.

(where it should have a little "lock tab" washer)

The easiest way I have found to track that down is to disconnect the linkage from the pedal rod and move the linkage at the carb to see what it feels like there.

If you have the ball/socket, or 90 degree angle rod type you can just take the rod out to makes sure it all moves freely, and determine where the resistance is.

I still get the same 'sticking'. This happens only when the carb has warmed up. My understanding is that the throttle plates should close on their own, without any external springs, right?

I guess my next step is to remove the linkage rod from the firewall and see if the carb behaves this way when it is all by itself.

Major PITA!!!

It is annoying as 12 year old valley girls with helium in their lungs... I would love to find the culprit too.... maybe you'd be kind enough to keep us posted?

    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
