[BMWCSRegistry] Webers

[Bill Proud]

A little side-note ....Weber 32/36 carbs have a PROGRESSIVE cam and pin linkage such that the secondaries dont start to open until the primaries are nearly fully open , so you can sometimes feel the point at which this happens .
Weber 38/38 are mechanically SYNCHRONOUS opening ......both sides are driven open by a pair of external little gear teeth ...so there should be NO sudden step in pedal-feel just a progressive tightening as you push harder against the spring .If you arent getting full power to redline with 38/38 s then I will bet that your linkage is restricting their opening at the top end . DONT overlook the fact that your motor torques around the motor mounts and that can affect the opening linkage . A fairly easy check to make is to disconnect the linkage at the carbs , open the carbs manually and verify they are fully open by looking down the holes . Block them open in that position (Stuff rags down em ) . Now check to see if the rest of the linkage will reach them ...........if not , I rest my case ......
Also ....do you have nice thick over-carpets on the drivers side floor ?? Sometimes they restrict linkage motion .
Check the simple stuff first !! 

If I might , I will repeat a warning I gave out several years ago .........Not all Webers that LOOK like 32/36 actually are . A true 32/36 has chokes that are 26 and 27mm  ( YES !! Brunhilda !! they DO , NOT 32/36 as you so often have thought !!) .....and those numbers are cast into the body of the carb . On my carb shelf I have several carbs that look exactly like 32/36s ....same size body castings, same mounts both ends  and all BUT they only have 21 and 22 mm chokes . BE CAREFUL OUT THERE !!
