How to use castor oil??

I wonder if you can run a bit of ATF through it?
In the tank, or sucked into the carb?

So how is the china girl doing with plain old castor oil? How does it ride (and smell?)

It runs great,,only 40 miles on this one and its pulling hard,runs smooth,,and smells GREAT!!!
At the price of piston and rings being so cheap and easy to install I don't care if it gums up much anyway,,these little motors should be freshened up once a year if ran hard like I do,,also I may try the 50:1 ratio,,Im at 32:1 now
