"update to my fuel problem, we

"update to my fuel problem, we went out today to test the engine, we ran about 3 minutes and it again slowed right down, missing then stopped. the fuel line was full as was the filter. we started it again started steaming and within 30 secs. it done it again but this time i took the fuel supply pipe off and strangely enough after about 10 secs. it revved up until the carb was empty. this happened a couple of times. it seems strangely enough as though it is pumping too much petrol. is this possible ? we only made it back to the marina by connecting the supply pipe until it slowed then disconnecting it. and so forth. this is really doing my head in. any ideas before i have to take it to a specialist?"
 
I think the plugs are OK .Soun

I think the plugs are OK .Sounds from the way the motor act that there is something wrong it the level control system in the carburetor ( AKA float and float valve ).
