My 2007 Toto recycler rear drive starts then stops after few seconds, has gas, seems like gas isn't gettin through .

Underneath the carb there shoul be a bowl screw head, usually 1/2in or 13-13mm. Loosen bowl screw a little, fuel should come out. If so, pinch off the fuel line to the carb from the gss tank or empty the gas tank. Remove the screw from the carb bowl. Inspect the hole inside the screw & the hole or holes thru the screw near the screw head for debris. Spray with carb cleaner & tap on hard suface to dislodge debris, you may have to use a small wire to clear these orfices. Make sure the float is free to fall down. You can remove the float, carefully as there is a spring & a needle valve at the back of the float in the middle where it is hinged. Ensure the needle valve is clean & the tube to the carb is cleam. After cleaning everything & clearing any clogs re-assemble carb & try to start.
