1974 Porsche 911 Throttle Cross Bar Kit,
Weber and Zenith* Carburetors

Product Description:

Cross Bar Kit, Weber and Zenith* 3-Barrel Carbs
Includes the reverse lever, pull rod from reverse lever to crossbar, two drop down links from the crossbar to carburetor and two pivot brackets that bolt to the intake manifold with included pivot balls.

*Please Note, when using with Zenith 40TIN carburetors: The original cross bar is no longer available from Porsche, and when using this aftermarket cross bar assembly on cars that are running the Zenith 40 TIN carburetors you will need to make the following changes due to the shape of the bar not being the same as the original.

1. When assembling the ball sockets onto the crossbar at the carburetor end, you will need to space out the ball socket by adding an additional nut to the ball stud before installing and tightening it to the cross bar. This will better position the drop down link so that it is directly above the ball stud on the carburetor linkage.

2. The cross bar preload must be correctly set, otherwise the bar will move back and forth. Refer to the factory manual for more details on this. 

3. The drop down linkages must be adjusted to be as long as possible without interfering with the air filter cans; this will position the cross bar arms to be as high as possible.

4. The cross bar may still need to be modified slightly if you are unable to get full throttle because the linkage is hitting the accelerator pump rod. If this is necessary, mark the linkage where it is hitting the carburetor. Using a small die grinder or angle grinder, carefully remove only as much material as needed to allow the carburetors to reach full throttle. Treat the bare metal with clear lacquer to prevent rust.

5. Finally, adjust the remaining throttle linkages and ensure that the throttle action is smooth and does not bind anywhere through the entire operating range.

If you are uncomfortable with any of these instructions, we suggest that you take the vehicle to an experienced mechanic to install these parts for you. The parts cannot be returned after you have modified them.
