Like Lewis,. I use a backpacking fuel bottle. The internal tank on my Honda makes refueling a pain sometimes, but I find if I plan ahead, I'm not caught short of fuel while out (I use my moter infrequently--mostly I run it a couple times a month just to make sure it still works). You can buy a spout for the bottle that makes refueling a bit easier, although slower. I like the security of the metal bottle. t Tom Smith & Jane Van Winkle Sandpoint, Idaho M15-345, Chukar
