Had a chance to work on the Zero a little bit more. Now that the decision on using the original supplied engine mount has been made, I proceed to install the engine and fuel tank. Using a push rod and file a point on it (see pic) as a tool to mark the fire wall where the throttle push rod will go through. Install the engine on the engine mount and set the throttle at the mid point between idle and full throttle. This is done because the throttle lever moves in an arc and will move the push rod up and down, this will provide equal space for up and down movement of the push rod. Mark the fire wall (see pic), and then drill a 3/32” hole. The kit supplied a ‘Z’ bend push rod for the throttle. Put the push rod through the fire wall and through the laser cut slot on former F2 and hook up the throttle and mount the engine. You should have a free moving throttle push rod.
