Re: [FWDLK] dual carb linkage adjustment



Thanks to everyone so far on my dual carb question. Dave, you're the first to mention the linkage for 55 or 56 Mopar duals has no slot. My engine is a '57 318. The rod that has no slots looks like an original piece, not a homemade set up, so this may be the correct linkage for a earlier dual carb set up. I will get it right I'm sure. Thanks again to everyone. All the info is very helpful. Nick.

Nick,

It sounds like what you have is the correct linkage for a 55 or 56 Mopar dual quad system. In those years both carbs opened at the same time, thus no
slot. Starting in 57, the linkage became progressive, so the rear carb
opened first and the front carb caught up latter.

I prefer the progressive style myself, even thought my car is a 56 with 57 Fury carbs. You might suggest a trade with a 56 owner who wants the correct
linkage and has a progressive linage to trade.

Subject: [FWDLK] dual carb linkage adjustment

I just picked up a '59 Sport Fury and it has a '57 318 engine with the
dual quad set up with the WCFB carbs.   What is the correct way to
adjust the linkage between the two carbs?  It was set up with both
carbs getting equal acceleration, which I don't believe is correct.
The rod between the two carbs doesn't look stock as it has no slot or
adjustment allowance.  It is basically a rod with two holes in it.  On
another car I have with dual carbs with AFBs there is a slot in the
rod between the carbs and an adjustment allowance.  I have a sheet on
how to adjust the idle mixture for the dual WCFB carbs but no mention
of throttle linkage adjustment.  Any info greatly appreciated.  Nick
