Re: Motorized Bicycle Take a Tip...Leave a Tip
That makes sense, the air trapped in the sight gauge line would prohibit gas flowing. Could still be done remotely if the line reaches high enough and has a fuel shut off valve at the upper end when the bike was not in use... say if it ran up the seat post and under the seat. Simpler though as you have it.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
