Hope you don't mind me jumping in. Ether is (obviously) very flammable and can ignite in your intake tract and air cleaner.
Most (not all) of my hard starting problems went away when I switched to ethynol-free gas. The ethynol is less volitile than gasoline; it vaporizes at a higher temperature. I think in the summer gasoline evaporates faster than the ethynol, so what started as E85 is now E55. The longer the gas sits in the tank, the harder it is to start. Ethynol-free gas here is about $5 a gallon, when you can find it.
