Dashpot System

  1. Slowly open throttle arm until dash pot rod is fully extended. Release throttle arm and measure time until throttle arm contacts stop screw. Time should be less than 2 seconds.
  2. If time is over 2 seconds, replace dashpot check valve and retest. If rod does not operate, check for bound linkage, or for clogged check valve or vacuum line. If they are okay, replace dashpot.
