Last night I spent an hour in our apartment garage getting the C70 ready for the move. I emptied out all the gasoline using the carb overflow tube. It took a long time to drain 3/4 gallon thru that skinny little tube, but it was a clean operation. In the past, I used to disconnect the fuel line from the petcock and drain it into the gas can, which can be messy and smelly, but quick. The method I used last night involved removing the gas cap, loosening the drain plug, turning the fuel petcock to reserve, and letting the fuel flow into the carb bowl and out its overflow tube.
It dripped for about half an hour, while I packed up all the tools and spare parts and removed the fragile legshield. I told the moving company that we are moving “a little moped, which is not working and is dry”, and they said that’s ok. The C70 is a bit bigger than a moped, but it is such a funky looking bike that people in the U.S. don’t necessarily think of it as a motorcycle or scooter, especially with the legshield off. They don’t really know what to think. Anyways, I hope that the moving goes smoothly!
