try cranking it for a few rounds, then pull the plugs and see what you have. if wet then it is flooding. maybe because of a float/inlet valve in the carb bowl that allows too much fuel in so it overflows and runs down the throat. it could also be a bad spark due to carboned plugs that don't really spark across the electrodes but rather trickle down the carbon trail.
if the plugs are dry then you may have a no fuel issue and may need to check out why.
check:
plugs
cap
rotor
points, condensor
plug wires
carb float level
compression
