Have a 24" Deluxe 2018 and its time to drain the gas. I removed the 10 mm carburetor bowl drain plug and removed the gas cap to let all the fuel drain through tank and bowl..Well to my surprise the tank does not drain completely even though the carb. bowl is dry...That means the drain opening is on the tanks side, not on the bottom?...What??..Why?? It leaves about an 1/8" of gas in there..No matter how I tilt the unit to the side or front, back....Left the unit outside with gas cap off to let it evaporate overnight....Anybody else notice this ??
