flooding carburetor 85 S&S
 
Just recently bought a new holley marine carburetor, while I was doing maintenance on the boat I noticed that gas was dripping into the front two barrells. I put the boat on the water hose and started it , it was hard to start because of being flooded . I then checked the power valve by having motor idling and turning the idle set screw in all the way. The engine did start to miss but didn't die. Does this mean the power valve is bad? Also is it normal for gas to be dripping in while nose of boat is raised above level? When I leveled the boat it stopped flooding.

I think this will get more views in the "engine" forum (you're in "audio").

If the engine runs with both idle set screws run all the way in, your PV is likely blown. HOWEVER, it sounds like maybe your boat kept running because the nose was high / floats are leaking.

It sounds like you really need to buy a rebuild kit to replace your needle and seats. I wouldn't pin it on the PV yet. If the boat keeps running while level and the screws run all the way in AND the jets not leaking, I would suspect the PV.

As stated above wrong section. Dripping is caused because of the floats. Even though it does not drip when the boat is in the water I would make sure the floats are set correctly.

As this is a new Holley carb, I would lean more towards the issue being with the boat not being level. I would throw it in the water and see how it goes.
