| CARBURETOR SPACERS |
 | RAISING A CARBURETOR FOR A HOPEFUL PERFORMANCE GAIN CAN BE TRICKY BUSINESS. BECAUSE THERE ARE SO MANY VARIABLES, TESTING DIFFERENT SPACER HEIGHTS AND TYPES
ARE ABOUT ALL ONE CAN DO. SOME BASIC PARAMETERS TO CONSIDER ARE THE RPM RANGE
YOUR ENGINE WORKS WITHIN, CAM PROFILE, INTAKE MANIFOLD, CARBURETOR SIZE, CAR WEIGHT, AND GEAR RATIO. RAISING THE CARBURETOR MAY OR MAY NOT GIVE YOU A PERFORMANCE INCREASE. HERE'S THE BASICS OF FUNCTION TO CONSIDER INSTALLING A SPACER. IT MOVES THE THROTTLE BLADES FARTHER AWAY FROM THE VALVE SEAT AND DAMPENS THE THROTTLE RESPONSE AT LOWER RPM'S. BUT, THE LONGER DISTANCE (VOLUME) MAY GIVE YOU MORE FLOW AND CONSEQUENTLY MORE POWER OVERALL. OUR SPACERS ARE MADE OF A HEAT RESISTING PHENOLIC RESIN.
