[DeTomaso] carb spacer and throttle linkage

[Cunnyngham, Christopher B (HSC)]

As the weather warms I'm dealing with some heat soak issues and percolation at the carburetor.  As part of the solution I'm installing a phenolic spacer between my Holley 750dp and H-M manifold.  I'm trying to plan for any modifications that might be necessary for the throttle cable and its attachments. Currently the cable is running at near perfect horizontal and allows for full open. However, adding a spacer is going to slightly alter that geometry.

With either 0.5" or 1" spacer the angle of the cable is going to be raised just off horizontal, obviously more so for the larger spacer. Does it matter if the cable isn't exactly horizontal? Do I need to either raise the manifold bracket or provide a lower attachment on the carb linkage arm? Or can I leave as is and just make whatever adjustment to be sure the throttle opens fully?

Thanks in advance.
