The problem comes when you try to mate it to the standard Beetle accelerator cable.
Over the years, I have seen some horrific attempts at cable routing.
On Andre_vdm's Beetle is one of the most effective solutions I've come across.


It gives full travel for the carb to open fully and it does not overstrain the standard accelerator cable and the alignmet with the accelerator cable housing is perfect.
Accelerator effort on the pedal is the same is stock.
Sometimes it does help to have a master machinist available - compliments to Andre's dad.
The manifold is an EMPI item. And very important CONNECT THE HEAT RISERS. Because of its manual choke, these Webers setup hates cold wet mornings until the manifod warms up enough to de-ice.
This setup has done about 20,000 km without any problems.
