If retrofitting the Explorer LD mouth/basebar throttle, it works best if the throttle arm on the carburettor is re-drilled approximately 3mm further in toward the pivot shaft.

This allows the throttle to go from idle to wide open with less travel at the mouthpiece, and still leaves some slack in the cable at idle to prevent accidental rev-ups.

This picture shows the general layout.


Drill a 2mm (5/64") hole. Place a piece of metal behind the shaft when drilling to prevent damage to the carburettor body.

When setting the cable length ensure the cable has some slack at idle (to allow for bends in the housing) but still has a small amount of travel left when the carburettor throttle arm strikes it's stop at wide open.

This photo shows how the throttle is best operated.


Left hand versions are supplied as standard to make VG/VB use easier (RH version shown).
