Help! I'm in dieseling run-on hell!

Hi folks-

I'm looking for suggestions on how to stop my '72 from dieseling like crazy EVERY SINGLE time I shut it off. It's getting to be really embarassing, sometimes it's so bad that the engine even revs up a couple thousand RPMs before it stops. The details: '76 bottom end (good compression), '82 E12 head, stock 1bbl Solex. I've adjusted the timing both ways and run 3 tanks of octane booster through it to no avail. The head is coming off for valve guides soon so I guess if there are carbon deposits down there somewhere that's when I'll find out. Still, I can't help but hope there might be a quicker solution... Any thoughts? Thanks!

keep the car in gear as you are about to shut the car off. As you turn the car off, pull your foot off of the clutch. Basically you stall your car into stopping. It stops the dieseling also. You will get so good at it that the car will shut off smoothly before too long.

...I've been shutting it off that way when there are pretty girls around, but I can't help but think it's bad for the clutch or the tranny or the motor mounts or something...

check the plugs and try adjusting the fuel mixture.

I had it too, but I adjusted the timing and fuel mix and now its gone, more power to boot. This on a tii though, im in SF too, if you want someone to drink beer while youre working on it let me know.

Yeah- I replace the plugs often because of the valve-guide oil problem. The mixture has been adjusted to what my mech. feels is best, but I'm sure the carb is wearing out. A Weber 2bbl and hotter cam are coming with the headwork so hopefully everthing will be good after that. What neighborhood are you in and what color is your tii? Cheers!

Hi Davin, regardless of the source of the problem, you can stop it from dieseling by simply putting on the e-brake, leaving it in gear, placing your foot on the brake and SLOWLY lifing the clutch. As the clutch just barely starts to engage, turn the key off and she'll shut right down. It is very important to do this as dieseling (I'm told) actually entails the engine running in reverse and is awful for internals...

Best,

Coop

...but fit poorly. They're 1989-casting 15" BBS wheels with a terrible 30 offset. They scuff even with the fender lips rolled. I'm thinking of having them machined down a little if possible because I love how they look so much. Cheers!

    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
