Big whoa back! EFI starts: the only things you touch are key on, brakes and start button, in that order. One or two revolutions and it runs unless, UNLESS there is something wrong. THEN you start finding out what is wrong. Stinking of gas after the first couple of tries, maybe then consider the flooded start procedure.
Anything with a carburetor requires a double secret probation process that may involve eastern incantations and virgin sacrifices. These various processes and sequences must be developed by the owner/operator/pilot and no one else. These additionally vary with ambient temperature, elevation, moon phase and are different between cold starts and hot starts.
EFI was invented to cut down profanity...
