I know it seems strange, but the intake manifold, where it bolts to the engine block does have two identical gaskets. The first time I saw that, I thought it was a mistake, but having two gaskets is correct. Perhaps they needed the extra gasket to get proper alignment for the governor shaft? To remove the governor shaft you will need to remove the recoil starer cover and pull the governor vane and shaft out through that side. The governor shaft just sits loosely in a rubber grommet on the engine back plate.
