Hello Everyone
I am having a problem with my O.S. 300 Twin, I go thru the priming procedure like the manual says to. Throttle fully open, choke applied and 2 counter clockwise rotation and the 2 clockwise rotation to prime the cylinders. When I spin her over there is so much raw fuel coming out of the pipes it is coating the tires on both sides. I gave the Air Bleed Screw a 1/2 of a turn counter clockwise which according to the manual should mix more air then fuel, I am using an EDI on board glow system to the glow plugs and all is working. I am at my wits ends with this thing, I need some advice and help on this one.

Thanks Morgan [&o]

what is your fuel tank height? , sounds like your syphening fuel. Tank shoud be centered on carb and fuel lines high looped. Even that may not be enough to prevent syphening.

You do not say if it starts after the priming. When I prime my 300 twin fuel also comes out of the pipes. I then set the throttle to idle, attach the glow driver and lightly prop backwards against compression and it starts right up. Does it start?
