Re: 2004 johnson 115 throttle body ?
if your primer red lever is in the wrong orientation, then you are pumping the manifold full of gas when you "prime the bulb"...could be a reason the plugs are soaked!!....the red lever is a bypass to pump gas into the manifold bypassing the carbs.....thus super enriching the mixture....if your motor is running good other wise, having the red lever in the wrong position will make starting difficult...
get a hold of the book and look at the orientation
cross your fingers this is your issue!!!!!!!!!!
easy fix
