Weber linkage parts source

[Walt Fricke]

I was using Weber 46s on tall manifolds. Then I installed TWM 46 throttle bodies to use Electromotive TEC3r EFI. I thought my Weber linkage would just plug in.

Not really - because the TWMs had a longer butterfly shaft lever arm, and that shaft is located higher up from the manifolds (and thus closer to the air filter base plate), I could not use the drop links (too long) or the TWM lever arms.

I dealt with the drop link issue by deleting the lock nuts and shortening the threaded bits, both male and female. Crude, but worked. I ordered a left hand die so I can make something better from scratch. So I have that part covered more or less.

I took the throttle levers off of my Webers, and put them on the TWMs. I didn't realize how difficult it is to get the fancy return springs to work, but I did and it works. So that part is covered, and the throttle is working.

But I want to replace the levers on my Webers. I checked with PMO's site, and with Pierce Manifold's site, and with Carburetion.com. I got Porsche part numbers for the levers (but not the lock washer, which seems needed because tightening the nut in the normal way seemed to cause a bind), but no real indication on whether these were available, nor what cost.

Suggestions?

PMO has the short lever arms as NOS and so do I, these were removed for the more typical longer ones.

I have 40's on pmo tall manifolds with similar challenges; could not get full throttle and also get full idle - partly cuz there was not enuf pedal stroke available before it hit the floor - I reomved the oem ball and redrilled the bellcrank and extended the effective lever arm - and fiddled a lot with the drop links; finally have them working OK and in unison -
