is there a fuel shutoff valve??
How Long Did this sit with out being used??
Sometimes todays gas formulas dry up and clog small fuel passages if it is allowed to sit a long time.
If you have a rubber fuel line going from the tank to the carburetor on the motor, can you pull it off (OUTDOORS) and have a catch pan handy, if the fuel comes out of the tank, then the tank part is ok, put the hose back then take it off the carburetor, does fuel come out of the hose??
IF you have fuel to the carburetor, does it get thru the carburetor?
that might be where it dryed up and pluged up
