    Can anyone tell me how much oil goes in the front case of a Fowler F-11
    With the F-11 there is no sight glass.
    Also has anyone had to move the pressure relief button on the front case as I have put a new new RCD starter/belt bracket and it hits the brackets?

    Thanks

    Ignore the last statement about the pressure relief valve as I forgot about the spacers!

    Used to be 2 cycle oil was gospel in the old days because everybody was afraid that if the rotor shaft seals leaked you would get less chance of detonation. Seals have gotten so much better. Haven’t seen a seal go in years. You want to lubricatethose gears and I know a lot of racers I like
    using Mobil 1 5w-30 or 0w-20 synthetic motor oil

    I have used everything from 2 stroke to 90w. Currently it has the same 60w that goes in the crank case (per littlefield).
