I'm finishing this engine rebuild, but encountered a problem. Original engine had a quad barrel carburetor (Weber was inside when i bought the boat). However this carburetor was shut and seized completely and beyond repair. So i bought another marine carburator matching the intake manifold. This is a Rochester 4mv one of its instances. I rebuild it, put new gaskets, needle and jets. But when i started cranking the engine I got some fuel overflowing. I wondered if it could be due to the electric fuel pump creating more pressure than the needle can take and it pops it up, thus continuing the fuel flow even when the float is supposed to shut it. Or could it be something with the carburetor rebuilt? I took it out and reassembled a again. Also since there was fuel leak into the cylinders, there is a problem with engine crank and I managed to remove 3 plugs, the other 3 I will try to remove tomorrow if there is still fuel in the remaining cylinders and the engine is not cranking. Or should I let the fuel evaporate over night since there is no carburetor? Sorry for the long post, just wanted to put all my questions in one post. Thx for help
