    I received the rings for this project today. I have 2 Johnson books, one is 30hp on up and the other cuts off at 10hp. I have nothing with my FD 20 specs in it. Are these specs correct.
    Ring end gap 0.007-0.017
    Connecting rod bolts 180 – 186 inch pounds
    crank case halves,
    center screws 162 to 168 inch pounds
    outer screws 150 to 170 inch pounds
    cylinder head 216 to 240 inch pounds
    Exhaust cover 60 to 84 inch pounds
    flywheel 60-64 foot pounds
    When breaking in the new rings, should I increase the oil ratio in the gas?

    Thanks,
