I should put about 2 oz. of pure casor oil into the gallon fuel bottle i have?

I was wrong, the fuel i have is the pink Omega 15%

i think i got it almost tuned out last night, i tuned the high ends to where it slightly increases rpms on the high ends, in this setting, i can get to idle down to 4,300 rpms. not as low as i would like, but i will work. it still when i tilt it up while idling, the rpms increase and then i eventually (about 10-15 seconds) flames out.
