Would a cable throttle device solve the problem??? I anticipate a similar issue so looking for a solution.... I am toying with a RH drive with the throttle linkage going from the right side up to the front of the engine....with a shaft underneath the water pump and back the left side to the mid engine bell crank.....phew!!!! with all the little connections the free play is deplorable... as anyone used these hot rod cable system.....?
