This adjustment must be made after the fast idle adjustment. Hold throttle valve wide open and close choke valve as far as possible without forcing. There should now be 9/64″ clearance (C) between upper edge of choke valve and inner wall of air horn. Adjust by bending arm on choke trip lever. When fast idle and unloader adjustments have been made, assemble baffle plate, coil housing gasket and thermostatic coil housing assembly on air horn. Set thermostat as specified making sure that hook on coil has picked up coil shaft lever.
