Re: Carbs on OMC Crossflow V6
Ahoy, Saperry. From your description, I don't think you have a carb problem, but I do think you have a fuel supply problem OR a S.L.O.W. problem.<br /><br />Fuel supply could be restriction of fuel flow, or air flow to the tank, any where before the carbs. If the VRO was disconnected, that could be a clue that it was done improperly and interfered with fuel pump operation. If you can get the engine to "open up" by pumping your primer bulb you have a fuel flow problem.<br /><br />Check: Vent for tank is not restricted, fuel pickup in tank is not restricted, primer moves fuel only one way and doesn't "back leak", oil inlet to VRO fuel pump is plugged, no air leaks in fuel lines, fuel pump squirts fuel into a plastic bottle, Sensors in oil tank are disconnected (what you have depends on what year engine).<br /><br />If all of that checks out, you might be going into S.L.O.W. because of a temperature problem. Remove and test the T-stat from the starboard bank, per your manual. <br /><br />Still no clear cause? Post us what you know.<br /><br />Red sky at night. . .<br />JB
