32-36 Linkage


Recommended Posts

I paid a little attention to my 32-36 yesterday.  There was significant slop in the fast idle rod and it would rotate in its pivots before doing its job.  I made a couple of aluminum washers and now it works like it should.

I have a few Webers and the other two did not have the same problem.  Worth looking at yours though, just in case. 

 

The pin on the linkage was worn, so I filled it and filed it round.

The auxiliary venturies  were very loose, so I shimmed them tight with a piece of paper, on the non-hole side (which was why I looked into the carb in the first place).

several cheap fixes.  drives much better now.  these little things do add up.

Some good ideas, I am trying to get some slop out of my fast idle linkage too.  One thought I am having, will paper hold up in the carb body, maybe thin brass shim?  You can get thin sheet brass at many hobby shops and hardware stores, maybe the paper will hold up, but if not that would be an alternative.

I repaired the worn pin on the rod that connects the vertical carb linkage with the carb by taking some brass tubing, cutting off a piece and pressing it over the worn pin.  I have a nice long piece left over, so will be glad to share an inch long piece if you want to repair yours.  Drop me an e-mail if you're interested.

I did the washer trick on the fast idle linkage, just did a cold start on the car tonight, finally getting enough throttle that it fires on the first try and doesn't die on the first couple tries, thanks for the tip!

HA!  You're welcome.  Mine fired right up today too, but I had not made the connection.  Once I was inside the carburetor I found several problems.  I reset the float height, tightened the power valve mounting screws and the accelerator pump discharge screw.  Put in a new gasket and shimmed the auxiliary venturies.  Apparently I was a little light handed while assembling things during the recent rebuild. 

 

I made some new cardboard gauges used the float settings in the Weber book I have.

I have been dealing with a very slow cold start, often accompanied by a backfire.  It sure will be nice if that is behind me.  Thank you for helping me diagnose the improvements :) it is hard to know which fix does what when I find so many to do at once.  Tom

    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
