    800 carb issues

    I have one of my carbs on the 110 hp twin boat which will not let the return spring on the throtle work. Its stiff and will stay wide open throtle unless a secondary spring installed to help pull it back. It looks like the shaft with the butterfly(throtle one) is corroded inside. Can this be taken apart and cleaned. I am worried that the little screws holding the butterfly on will not come out.

    Don't take the butterfly out. Take the carb off, and soak both ends of the shaft from the inside of the carb with PB Blaster. As the linkages ae connected together, when you get it loose it will return like the other one.

    I fix them all the time,take a die grinder to the back side of the screw & grind it flush with the shaft & the screw will come right out with a good screwdriver.

    Remove shaft clean out bushing or drill slightly to relieve a little of the plastic bushing.

    I'm sure you already know this...but please do this with the carbs off of the engine. The last thing you want to do is try to fish a screw out of the motor or worse not know you dropped one until you fire it up and crater the engine.
