Engine Starving For Fuel

[GrouchyOle'Man]

Hello, It is a 150cc Peace Scoooter. Fuel is in the carb. Everything else checks out O.K. although I have not performed a compression check. One day it was being run in the rain and just died. Valve adjustment set at .004". Engine may start and run short period with carb spray shot into Intake Manifold through vacuum fitting. A member on this site has stated that Low Float Bowl Level (fuel not covering the Pilot Jet and/or Bad Timing) are 2 things to check if the engine will not induct the fuel from the carb. Does anyone have anything to add to this? Thanks.
