    Tried the 25 degrees again. Kills the motor every time. Went back to 16 degrees, and shifts without stalling. I'm thinking that 25 degrees is too close to MBT at idle.

    Again, what size camshaft (duration @ .050") is in the engine? Don't say, "I don't know"...find out what it is. Also, is the ignition timing fully synchronized?

    Duration @ .050": intake 235°, exhaust 243°.
    Lobe Lift: .3590" intake, .3690" exhaust.
    LSA: 114.0°.

    I'm not sure if I've mentioned, this is in a boat turning a fairly large prop (4 blade bravo 30° pitch).

    It just seems unusual to me. That camshaft should like 25° of idle timing, better than 16°. I hope your ignition timing is synchronized (Link).

    Thank you for your help. I'm going to double check my synchronization.
