Weber 40DCOE throttle linkage and soft mount questions

Hi Guys!

Hope you all had a Happy Seven Weekend ;-)

 

A few weeks ago my carbs caught fire so I sent them for a rebuild.

I did it in a bit of a hurry and forgot where the throttle cable bracket attaches to the carbs .... yes I know...thats why we have cameras on our phones ;-) Or a working brain in our heads!!!!

I think it is attached by the bottom cover screws closest to the motor, but not sure. (in the picture I have attached it to the front screws and I think that's wrong.)

Also not sure where the return spring attaches to the bracket.

It's a Crossflow 1600.

Mahalo for the help!

Mines is mounted to the inboard screws, pointing inwards.

There appear to be differences in bracket construction..

the collett may be either inside or out.

position the collet so its centered.

On the soft mounts...I have used Thackery washers on the bottom studs with the rubber doughnuts on top.

The washers have been compressed to .040" between coils. The doughnuts I have compressed until there is about a penny ( .065") width between the cup washers.

But i just found this info on an Elan forum and it seems to be exactly what i am looking for.

 

1) Thackeray washer: until there's a 0.35 - 0.50 inch (0.89 ? 1.27 mm) gap between the coils, or...

2) Rubber Grommet: until all slack is taken up between the nut, cup washer and rubber grommet (ie, the stack just goes solid), then tighten the nut another 1 1/2 turns, ensuring that the "V" in all grommets is equal. Since the M8 nuts have a 1.25 pitch thread, 1 1/2 turns is equivalent to 1.88mm (0.074") of crush/ pre-load... or roughtly 2 mm (0.08")

I cannot thank you enough for your help. Brilliant!!!!!

Looks like the diagram shows the bracket with the collet out...I think mine was like yours...inside.

Where did you "zip the cable to its fixing" ?

At the bottom,  the cable anchor.

I didn't install it, the shop that built up the car did.  its not in the picture anymore because it worked loose and i cut it off recently since im removing everything soon.

But I would definitely have it, or something to retain the cable.

 

Another thing the shop did was zip tie the sparkplug boots to the distributor.
