  • starting problem

    I Have a 47 Champ which starts right up when cold but after runing for awhile is hard to start. But if and when I use a little starting fluid starts right up.
    Has anybody have any thoughts

    Have you tried choking it when warm? Perhaps the caruburetor is losing gasoline when warm.
    Have you checked the spark at the plugs when the engine is warm? Perhaps the spark becomes weak when the engine is warm due to faulty ignition points or other electrical malfunction.

      Is your heatriser functioning properly? In other words is it opening up as the engine warms up, if it doesn't open it could be boiling the fuel out of carb- hence the restart with starting fluid. Todays fuel, specially winter blends, could have 10% or more alcohol content, which lowers the vaporization point. Lou Cote [8D]

        Run a compression test also. Weak compression when hot could make the other things suggested worse.
