How do I replace the 2 existing pieces of tube that run from the small plastic bottle below the carb (in the inverted installation) to the engine?
Refer to the installation manual for the rotary valve on page 13-2 and the instruction sheet included with your kit for changing over for inverted use. Also, look at page 13-2. Hose #4 is on the bottom of the engine, which is now the top for an inverted engine. Turn this fitting sideways to get the hose on and miss the motor mount. Refer to the attached pictures to see how to remove the plate to get to the other fitting for Hose #5. See the attached pictures.
