Turn the motor upside down??, Heck noway man, you drain it then
put the top screw back in. Just leave the top loose enough for the
air to come out. Then squeeze the oil in the bottom hole until it
comes out of the top hole ( around the screw ). Then tighten down
the top screw and pull tube out and replace the bottom screw.
You are all set now. Good luck!!
Yup. Thats the way. by filling it up from the bottom, you push all the air up and out, and you can be sure it will fill up evenly.
