Tii linkage question


Recommended Posts

from the gas pedal linkage to the injection pump linkage it has two holes for the rod to go into. should it be in the hole towards the front or back of the car? or is it an allotted adjustment to make up slack?

my throttle body is not opening all the way ,this looked to be a solution ?

have not swapped it to the rear hole yet as I had no time tonight

thanks in advance

Can you answer this first?

I assume you are saying when you go WOT (Wide open throttle) at you pedal, (pedal to the floor), the throttle plate does not open fully.

Need to know, when you go WOT, does your Kugelfisher go all the way to P4?

P4 is the the fourth position in the cogged type lever. Does P4 line up with the hole in the body of the pump?

P4 (WOT)






P1 (Idle)


The hole in the body of the pump


Tool (the orange pen is pointing at it) inserted threw the cogged lever into the hole in the pump body


The reason I ask, if neither the throttle plate nor the pump is WOT, the adjustment needs to made to affect both, usually at the pedal box.

If it is just the throttle plate not opening, that may need adjustment at the pinch plate on the intermediate shaft(s) just below the throttle body.

I understand that the butterfly plate is not opening fully but we need to know is the Kuglefischer opening to P4 with the pedal to the floor? Same question I asked above. We need an answer to that question.

There is not a link to those photos, I took them in the shed and posted to my Photobucket account. I can e-mail them to you if you send me an e-mail

Good stuff already posted. Watch out if you move the firewall linkage connection upward - it might contact the rear air cleaner snorkle and you certainly won't get WOT from the pedal.


The other area to check is the vertical connection to the throttle body.

Hole to the front is the correct location for the linkage.

Listen to Bill he knows what's what. It's tough to get a sense of the P4 alignment without the tool shown in Bill's photo, though, while the pump is in the car. Some folks use an allen wrench I believe.

Instead of my wife's foot, I use a small spring clamp to hold the pedal on the floor stop while I'm checking WOT settings under the hood.

If you don't yet have a set of tii tools, keep your eyes open here and on ebay. They make the initial linkage setup (which you will be doing shortly) a breeze. Oh, and download a copy of the tii tuning guide. Think it's available via the tii register, along with a video.

Good luck!

    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,

    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
