I have the manual choke and when my tubes plug, a little choke will keep
me driving ok.

There is another cause of rough idle, but it goes along with oil
spitting into the air filter. No oil spits, not the trouble.

Is usually isopropyl alcohol. Methanol tends to be a bit
too corrosive, ethanol would work, but isopropyl is easier to
deal with and produce with extremely low water content.

There are a few other solvents that grab water almost as well
as light alcohols, but tend to have varying effects on
engine gaskets seals etc.

Or you could drop a lump of sodium in your tank. It is actually
stored in kerosene, but will absorb any water in the area with
impressive vigor. And then to get rid of the resulting sodium
hydroxide, you add shredded aluminum which reacts with the NaOH
to produce hydrogen gas and aluminum hydroxide. Give the hydrogen
to your fuel celled buddies and use the aluminum hydroxide as
underarm deodorant.

If you need any more chemistry tips, just ask. >:-)
