Q-SERIES,650CFM CIRCLE TRACK CARBURETOR,4150

BRAND NEW HOLLEY QUICK FUEL CIRCLE TRACK Q-SERIES CARBURETOR, RED & SILVER FINISH, 650 CFM, MECHANICAL SECONDARIES, COMPATIBLE WITH GASOLINE

QUICK FUEL TECHNOLOGY Q-SERIES CIRCLE TRACK CARBS ELIMINATE THE GUESSWORK AND OFFER SUBSTANTIAL ADVANTAGES IN ADJUSTABILITY, CONSISTENCY, AND PREDICTABILITY. SINCE RACING AROUND A BANKED OVAL PUSHES FUEL TO THE PASSENGER SIDE OF THE CAR, Q-SERIES CIRCLE TRACK CARBURETORS FEATURE DIE-CAST ALUMINUM FUEL BOWLS WITH INTERNAL BAFFLES THAT ELIMINATE SLOSH. BOWLS ALSO FEATURE AN INTEGRATED FUEL CHUTE THAT SUBSTNTIALLY REDUCES AERATION & DIRECTS FUEL TOWARD THE MAIN JET PICKUP AREA.

TO ASSIST IN FLATTENING OUT THE FUEL CURVE, SCREW-IN AIR BLEEDS ENABLE FINE-TUNING OF BOTH THE LOW- AND HIGH-SPEED SYSTEMS, WHILE A PROPRIETARY BOOSTER DESIGN ENHANCES CARB SIGNAL WITHOUT RESTRICTING HIGH-RPM AIRFLOW. HELPING DRIVERS PUT THE POWER DOWN IS AN ADJUSTABLE QUICKLINK SYSTEM THAT ALLOWS CHANGING THE OPENING RATE OF THE SECONDARIES TO 40-, 60-, OR 100 PERCENT. EQUIPPED WITH ROLLER BEARING SEALS WHICH PROVIDE SMOOTHER THROTTLE RESPONSE, LESS WEAR ON SHAFT & LONGER LIFE.
