It has been a godsend for them to not have to cover problems created in this manner.
And here is the problem, simply performing a storage process will not fix the problem.

The solution another posted advised is actually a better approach. By flushing the engine with "proper" gasoline, you will accomplish more than just following any manufacturers guidance but doing so while sticking to gas/alcohol mix as your fuel.

The phase separation does not start at x weeks, it actually stars almost immediately, and by week x it is clearly visible.

Combine the fuel deterioration with the impact of the alcohol solvent on fuel system components and you have a process where the carb is slowly and constantly being exposed to particles and gummy material and trying to fight that. If you use the motor all year long you will greatly delay the clogged carb problem, but likely not completely avoid it. And when you then store the motor off-season, the particles and gummy material sit in the tiny passages and continue to wreak havoc. Sometimes you will start the motor the next year and it may run poorly for a while and then seem to clear up, only to be worse the next season as the cumulative effect of buildup takes place in the carb. In other years this happens in one season.

Flushing the engine with non-alcohol and premix helps as the oil keeps the particles and gummy material from drying out and totally clogging the passages. Its not a 100% solution, as even with non alcohol gas this process happens, its just much slower.

Bottom line, alcohol gas is not good, and just draining the gas and running your motor dry of fuel will not assure you of no clogged carb problems.

Not sure there is an actual fix, just degrees of worse or better.
