I just stuck $600 into my engine. I got a new water pump as well as a new starter. when I picked it up it ran fine. So I took it out fishing and I ran into a problem. It would not start and go unless I held in the electric choke and started it in gear. If I start it in neutral it will not fire up. If I give it choke while it is in neutral it will fire up for a second and then it will die out. I changed the gas line and the fittings because I thought it may not be sucking the gas. Anybody have any suggestions? It is a 1988- 35 horsepower Merc tiller handle. Any help would be greatly appreciated
