By the way, I think that it is more important to know
and prevent the rust build up from happening again.
This is mainly caused by left over fuel inside the motor
after the motor has been ran and then kept.
Try to make it a habit to, after each day of running the
motor, to drain all the fuel from the tank and have the
motor run off all remaining fuel until the motor dies out.
This will insure that no fuel residue remains inside the
motor which causes the rust that you are encountering.
Some other people run the motor at idle and then pinch
the fuel line to cut off fuel supply.
Personally, I use the first method.
It may likewise be a good idea to use After Run Oil after
running out all the fuel. This will help lube the inner parts
of the motor and keep it in shape for longer period of time.
Hoep this helps further.
