"Can anyone give me a list of items to check please; I was out on the boat for a good three hours, towed it back home, put the mufflers on to clean out and the engine wouldn't start, it turns over with ease, the safety switch is ok (I tested it) new plugs put in (because I had them as spares), havent tested the spark yet, there seems to be a definite smell of petrol after I have tried to start it when turning it over a good few times; all help will be welcome, cheers...by the way...great site, just found it."

It is quite common that a motor will run fine and upon throttling down a clog stops the float from closing properly and the engine floods out."

cheers"
 
"You have to pull the carb&#40

"You have to pull the carb(s), disassemble, clean, and possibly add a kit.
