The Kuryakyn adjustable enrichner provides the user with three levels of fuel
concentration for ease of starting and improved warm up. The further the enrichment
knob is pulled up, the richer the air/fuel mixture will become. Cold starts on cold
mornings will require maximum enrichment - the knob pulled all the way up with the
stop pin resting on the top surface of the enrichener body. After start up or as the
engine warms, rotate the control knob so the stop pin will drop one step at a time.
Continue to lower the enrichener until the engine is warmed sufficiently for smooth
operation. Warmer temperatures or partially warmed engines will not require maximum
enrichment.
NOTE:
• Set the enrichener in the run (lowest) position as soon as possible after the engine has
started to prevent fouling of the spark plugs.
• In the lowest or “run” position, the stop pin will not be seated at the bottom of the
lowest guide slot.
