I am trying to troubleshoot a flooding issue and am wondering how the electric priming system works. I have a 1988 20HP (J20ECCA)
I have confirmed that the primer is not leaking fuel when not engaged. I pumped the fuel line bulb with the engine not running, nothing comes out of the primer. However when the engine is running, I do see fuel flowing through the primer lines. (I've put clear fuel lines on).
It appears that the fuel is flowing from the line that goes from the bypass cover to the primer. What is the purpose of this line? Is it part of the recirculation system?
My understanding is that the larger line that runs from the crankcase to the top of the manifold (#27 in the crankcase diagram) is the recirculation line.
