2X4 Return Spring Question By John - 04/07/2002 4:08:17 PM; IP 142.177.8.17 The operating linkage on a 2X4 carb set-up seems to have an inherant design problem with respect to how the throttle return spring operates. The more the bellcrank opens the throttle, the less return effect the spring has, even though the spring is exerting more force as the throttle is depressed. Eventually the spring does nothing to assist with throttle return. This can be disconcerting when driving. I've tried different strentgh springs as well as dual springs. I think the best idea is to fabricate some bracketry which will cause the spring to pull back directly on the control rod that fastens to the bellcrank from the throttle pedal assembly. Has anybody any better ideas?

This thread, so far...
