Guys I need some help, I have a 4 stroke .70 and it fell into water over the holidays. It was all rusted and wouldn't start  so I decided to take it apart. When I finished cleaning it and I have assembled it, there is no more compression. The engine won't start and whenever we plug the ignition in and try to start it, it make a strange bubbling sound. I think there is too much fuel in the piston or carburetor. I got so frustrated that I just went to go buy a new engine.
