ANTI-PERCOLATOR ADJUSTMENT: Back out throttle lever adjusting screw. Anti-percolator should be checked after metering rod setting and installation of metering rods on carhureter.
Do not disturb metering rods or pump adjustments.
With throttle valves tightly closed, adjust lips on anti-percolator arm to depress anti-percolator stem so indicator line is flush with top of anti-percolator plug. Since there are two anti-percolator units on this carhureter. great care must be taken so that an even adjustment Is made on both
BPS.
UNLOADER ADJUSTMENT: With throttle wide open, dis-
tance between upper edge of choke valve and wall of air horn should be 9/64 inch. Check with T109-34 gauge. Adjustment can be made by bending lip on fast idle connector link. If unloader is adjusted properly, with throttle wide open move choker valve wide open and choker valve will be locked in wide open position. Closing the throttle will re-lease choker valve. Choker trip lever is notched out for this setting.
FAST IDLE ADJUSTMENT: Hold choker valve tightly closed and adjust fast idle arm screw to give .030 inch opening between edge of throttle valve and bore of earbureter side opposite port.
