Solex 4A1 Rebuild ↗

Owner project on a 320/6: strip the four-barrel Solex 4A1 (eight screws release the top), clean the idle jets and needles, check the main jets and fit fresh gaskets. Explains how a clogged idle needle on one barrel pair gives a rough idle and how the auto-choke housing position sets richness.
