Arch, funny you mentioned gassers....the walbro carbs don't allow fuel in unless the engine is turned or at least rocked back and forth between TDC and BDC. A check valve in their vents is of no consequence regarding engine flooding. I intend to use the device in that set-up also for the SAP 180 to help reduce gas fumes when transporting the crate.

NO out, but lets air in??? right??
Do you pull it off when you fuel??
Otherwise the tank will blow up....
