Just how far is too far. See my post of 04/23/01.
Just one thing, take a spare can of gas if you run a machine that uses premix or a spare can of 2 cycle oil if your machine "mixes its own". It is really a humbling experience to have your ped go cough, whezze, sputter, dead. You start running thru Don List to fix moped problem nothing works, then you juggle the ped w/the gas cap off and no slushing sound. Outta gas, in the middle of a rural area without a gas can, 2cycle oil is similar to being up the creek w/o a paddle.
While hauling a spare gas can may not be a pretty sight, as my biker friends say, pretty don't getcha home unless you're a chix."
