Lather, rinse, repeat.



If you don't get anywhere after an hour or so, leave it overnight and go at it again the next day.



Related: always run your engines out of gas before you put them away for storage. Of course, follow the manufacturer's recommendations, but if you're only going to do one thing - put it away without gas in the lines. This tends not to have as great an impact on cars because we dilute and burn the gas before it has a chance to separate.

This sounds like how my partner winterizes his motorcycles.
Would you recommend the carb cleaner on a routine maintenance basis?
