AIR CUT-OFF VALVE

INSTALLATION

PLEASE REFER TO YOUR CLYMER, HAYNES, OR HONDA WORK SHOP MANUAL FOR LOCATION AND INSTALLATION PROCEDURES.

AIR/FUEL MIXTURES MUST BE SET WITH USE OF MERCURY MANOMETERS ALSO KNOWN AS CARB-STIX OR VACUUM DIAL GAUGES. THE CARB STIX ARE THE MOST ACCURATE, AS THEY ARE ALL SET BY SIGHT, USING the number 3 CARB AS THE REFERENCE LEVEL. THE NUMBER 3 IS THE CONSTANT FIXED FLOW CARB, SET AT THE FACTORY.

DO NOT ATTEMPT TO SET BY EAR, OR BY JUST GUESSING, THE RESULTS CAN BE ANYWHERE FROM PATHETIC TO DISASTROUS.

IT IS ALSO CONVENTIONAL WISDOM TO REPLACE THE CARB-TO-MANIFOLD "O" RINGS. VACUUM LOSS CAN OCCUR THERE, AND MIMIC THE EFFECT OF A BAD AIR CUT-OFF VALVE. PASTE A NEW SET IN WITH VASELINE, AND MAKE SURE THEY ARE SEALED IN WITH AN ETHER CHECK.

DO NOT DEVIATE FROM THE BOOK SETTINGS. WISER PEOPLE THAN ALL OF US DESIGNED THIS VERY EFFECTIVE AND EFFICIENT INTAKE AND CARBURETION SYSTEM!!!
