THROTTLE CABLE BRACKETS

APD’s billet Throttle Cable Brackets are the perfect addition to any Enforcer series or Max Speed carburetor. APD offers 3 versions of their cable brackets, and all brackets are made from 6061-T6 aluminum, anodized black, and come standard with return spring bracketry. The Standard and Max Speed standard length bracket can be utilized on applications that are not utilizing a starting line enhancer; while the Max Speed Long bracket can be used with applications using a starting line enhancer.

ENFORCER ELITE BASE PLATE THROTTLE STOP

When paired with one of our Enforcer Series 4500 carburetors, the Enforcer Elite version of APD’s under carburetor throttle stop corrects the problems commonly associated with many other conventional baseplate throttle stops. The Enforcer Elite Throttle Stop has a fuel circuit that is channeled internally from the carburetor, through the body of the throttle stop, and exits under the throttle stop blades. This feature mimics the fuel draw characteristics of a carburetor without a throttle stop under it and because the channel continues to see a strong signal while the stop is closed, the overall carburetor calibration doesn’t need to be nearly as rich. As a result, th engine air/fuel ratio can be kept optimum which delivers smoother throttle stop graphs, better throttle response, and leaner, faster back half charges.
