| The Enrichener Knob is a friction function device. When mounting the knob, do not overtighten the mounting nut. The resistance/friction on the enrichener cable can be adjusted with the knurled nut. | The Enrichener Knob is a friction function device. When mounting the knob, do not overtighten the mounting nut.

| The fuel for the enrichener circuit is drawn thru a fixed jet in the float bowl. The air for the enrichener circuit is taken in thru the banana shaped inlet at the top of the carb face (see the face pic above). Sometimes when the enrichener cable is moved, or the carb has been taken off the manifold, the valve piston does not properly seat into its cavity on the carb. If that happens, additional attention must be given to properly reseating the enrichener valve piston. | The fuel for the enrichener circuit is drawn thru a fixed jet in the float bowl.
