Cleaning the Idle Circuit in a Solex Carburetor

Len Sokoloff /

1959 Mercedes-Benz 220S cabriolet

Does your car stall every time you come to a stop? Can you not keep it running without giving it gas? One possible cause of this problem is a clogged idle jet or idle passage in your carb(s), particularly if this came on all of a sudden. This is the only thing in the Solex carburetor that would cause this. There may be other issues external to the carb that might cause this, but I won't get into that here. Since cleaning the idle jet and idle passages is so easy, I would suggest you start here and rule out your idle circuit as the problem.

This is the procedure for cleaning out the idle jet and its related passages.

Enjoy your renewed, nice, smooth idle!
