I went out to my boat to run the Atomic-4 since it hadn't run in a couple weeks and I am taking my wife out today. Engine
problems are not an option, so I was just looking to run it for a little bit.
When trying to start it, the engine
would only run with nearly full choke and a small amount of throttle. As soon as I closed the choke a small amount the engine would die. When I went below to see if there was an obvious problem, I touched the inline secondary fuel pump
and found it very hot. It was hot enough to have heated the fuel
line between the pump and the engine significantly as well. I disconnected the power to the pump and attempted to start the engine again. After a couple of minutes the engine not only running, but was idling fine without any choke.
I am assuming that the fuel pump
raising the temperature of the gasoline was the reason for the problem. Is that reasonable?
