In my
's Honda BF50A, which I presume must be its original 2001 engine, at the end of the season I drain the carb bowls as per the Service Manual, which is quite easy to do. I then empty the fuel tanks and use the remaining fuel in my other vehicles. About the fuel: In my marine and other smaller engines (lawnmower, generators, motorcycles) I make a special half hour run down two counties south to get some ethanol-free 89 octane there in supposedly "rural" Fredericksburg, Virginia, where they're allowed to sell "the good stuff" by the EPA at the pump. Every time I make such a fuel run I make sure and let my congressman and both senators know how much of a fuel-wasteful pain in the ass it is to have to do this to get fuel that won't harm my engines just because every nitwit with Presidential aspirations, or who's ever ordered pyjamas with the Presidential Seal off Etsy, feels obliged to stroke off the Iowa Caucuses while reciting "The Ethanol Pledge" to get enough wind in their sails to make it to the New Hampshire Primary. Ethanol is the Devil best avoided.

I might also add an ounce of two of Marvel Mystery Oil at subsequent topoffs. Knock wood, my Honda has seemed pretty happy with this regimen.
As far as managing fuel transfers and such, I have found this battery-powered fuel transfer pump for under $10 from Harbor Freight very useful: https://www.harborfreight.com/battery-o ... 63847.html
