CARB ADJUSTMENTS

ALWAYS BE SURE THAT YOUR ENGINE IS WARMED UP, AND THAT THE CHOKE IS WIDE OPEN, SLOW ENGINE SPEED DOWN TO ABOUT 800 RPM THIS DONE BY TURNING IDLE SPEED SCREW LOCATED NEAR THROTTLE LINKAGE ON DRIVERS SIDE OF CARB, NOW START WITH THE MIXTURE SCREWS THEY ARE THE SCREWS ON FRONT OF CARB WITH THE SPRINGS, TURN THE DRIVERS SIDE SCREW CLOCKWISE SLOWLY UNTIL YOU SEE THE ENGINE START TO SLOW DOWN, THEN BACK THE SCREW OUT 1 FULL TURN, THEN GO TO THE MIXTURE SCREW ON THE PASSENGER SIDE, TURN THE SCREW IN CLOCKWISE, WHEN ENGINE STARTS TO SLOW DOWN BACK SCREW OUT 1 FULL TURN, NOW RESET IDLE SPEED AGAIN TO 800 RPM, THIS IS THE BASE IDLE AND MIXTURE ADJUSTMENTS, YOU CAN FINE TUNE IF DESIRED, REMEMBER THAT BY TURNING THE MIXTURE SCREWS IN CLOCKWISE YOU LEAN OUT THE ENGINE, AND BY  TURNING COUNTER CLOCKWISE YOU RICHEN UP THE ENGINE, ONCE YOU OBTAIN THE BEST IDLE  YOU CAN EXPERIMENT BY GOING IN OR OUT A VERY LITTLE AT A TIME, BUT REMEMBER TO DO IT EVENLY.

A WORD OF WARNING ANY ENGINE THAT HAS A VERY HIGH LIFT OR LARGE DURATION CAM IT BECOMES HARDER TO GET A GOOD FEEL ON THE MIXTURE ADJUSTMENTS, THIS IS CONSIDERED NORMAL.

A FEW HELPFUL HINTS TO CONSIDER, TRY TO KEEP CARB, FUEL FILTER, AND FUEL LINES AS COOL AS POSSIBLE, ENGINE RUNS BETTER IF THEY ARE.

AUTOMATIC CHOKE RED WIRE MUST BE HOOKED UP TO 12 VOLT KEY CONTROLLED IGNITION, ON AND OFF WITH KEY.
