Engine vent line question
Never had this happen to me before yesterday, but, will an engine continue to run (albeit not very well) with the vent line disconnected from the muffler? I was flying yesterday and except for my first flight, the engine seemed to not be generating very much power. In fact, full throttle was like 1/2 throttle. Halfway through my 3rd flight, the engine began to waiver and run unevenly, almost dying a few times. I landed, attempted to re-fuel, and fuel started pouring out of the cowl. When I removed the cowl, the vent line was dangling, totally off the fuel tanks brass vent line hook up. The engine is s Saito 72. Can it still run without the vent line attached?
