Okay, bear with me...doing some work on the museum's '46 RC70.

How does the gas in the tank get to the carb?  I must've been asleep in autoshop class on the day they talked about fuel.  However, without a fuel pump, how does the fuel get from the sediment bowl, let's say, to the carb?  Does the carb produce suction to deliver the fuel from the sediment bowl?

Just like to know.
Thanks in advance.
