Yeah, check it out, these things usually come with carb kits or are available from Cb Peformance-
Look at where the linkage is attached to the carb on the left.
And extra offset bolt is there next to it.
8mm hex size shaft with stud on one end and threaded on the other.
I guess using one of these means you have to use updated drop links. I drill the balls off the carbs and use the new stuff - for Solex's, it's looser yet has less play than the ball-sockets of old.
Very easy to adjust too.
Those linkage arms are from the Baby Dellorto / Weber 34mm kits.
I'm going to update all my throttle linkage up to the pedal with this stuff and see how it goes.

I think the reason most people dont compensate for the offset on the carbs is their linkage it attached at the Air-Filter- which has the same offset as the carb, 356/912's have the linkage straight across the top creating the problem.
Actually the 356/912 linkage design is great other than it's mounting = being attached to the engine / fan housing it transmits vibrations down the linkage to the carbs wearing out the carbs and linkage faster and causing more frequent adjustments.
The aftermarket VW kits eliminate this being attached to the air cleaner base where the linkage top and bottom encounter roughly the same vibration.
. ...Just something to think about.
