Rebuilt quadrajet is installed on my '75 Cadillac Eldorado. When the accelerator pedal is fully depressed, the secondaries are not 90 degrees vertical - they're maybe 80% of that. Is that normal? If not, what should I do to adjust? The accelerator cable is aftermarket and may not be exact OEM size (should be within an inch though), so that might impact things a bit. Interested in any thoughts y'all may have.
