| Pocket bikes in general use a gravity feed fuel delivery system for the carburetor. Therefore if you mount the fuel tank below the carburetor you will get no fuel flow.
BUT.
Walbro carburetor's have an internal fuel pump that uses the crankcase pressure and vacuum to power the pump within the carburetor. The best thing you can do is get a Walbro carb off a chainsaw that uses an external pulse line. Fabricate a flange to bolt the carby that will press into the stock manifold then drill and tap a hole into the crankcase for a small hose nipple to screw into that you plug the pulse line into. This drives the fuel pump and everything works hunky dory and best of all it's easy to tune and make setting up a throttle linkage very easy for use with an RC servo.
The short.
When a Walbro carb is primed it is able to pump fuel from the tank and the engine will operate no matter which angle the carburetor or engine is sitting. The fuel tank can be above or below the carb it doesn't matter.
