Most of the gasoline driers are alcohol based.  Alcohol has an 
affinity for water which is one of the more difficult parts 
of home distilling for motor fuel.

As mentioned Stoichimetric ration for gasoline is 14.7:1, 9.00:1 for
ethanol, and 6.45:1 for methanol.  What this means is that for proper
combustion you need very close to the ratio of air to fuel.  Anything less
is a lean condition and can cause misfires, any thing more is a rich
condition and is wasted fuel.  You can see from the above you need more than
twice as much methanol as gasoline for proper combustion.  

This is a cause of the misunderstanding of alcohol atomization.  Large jets
in carburetors spill fuel in a larger cross section and the turns of intake
passages can cause fuel puddling.  Both of these conditions make atomization
more difficult.  Fuel injectors largely solve these problems by injecting
fuel right at the intake valve so there are no puddling problems and
injector pulse and swirl patterns break up fuel into much smaller droplets.

By the way, computer controlled fuel injections operating on a closed loop
can compensate for the different mixture requirements.

I am glad the world has moved away from carburetors and points, I have spent
too much of my life trying to make both work.
