Re: Removal of shift rod
Most models have a bellcrank under the carburetors. Loosen the screw that forms the fulcrum of the bellcrank and spead the fingers at the shift rod end to relase the pin that holds the shift rod.
Reaching the screw will be easier if you disconnect the control cables.
There is a nylon bushing in the swivel at the top of the shift rod - try not to lose it.
