DF 140 starving for fuel

[johnscreek]

DF 140 with 520 hours. Changed plugs, upper and lower oils. New fresh non-ethanol gas. Started right up in driveway. took to ramp started up backed off and idled for 5 minutes. Engine cut off. Will start but sputter out soon. Primer will not fill up. Any thoughts?

Normally you will find a restriction on the suction side of the bulb when you have this condition. The proble could also be a plugged vent on the fuel tank

I would check any filter or screen that may be in the tank and make sure the fuel tank vent is clear.
