I thought I would share this in the hope that it helps someone else at some point.
My little Yamaha Malta 3 hp tender engine was a lovely engine and worked flawless until late last year when it started playing up.
I have tried a couple of times to fix this and think now it is achieved. Symtoms were it would sometimes start sometimes not and when it did it would cut out so a real pain.
After stripping the carb down several times and cleaning I noticed that fuel was leaking from somewhere. I tracked this down to the big O ring/gasket type seal between the float chamber and the carb body. I think the carb was leaking petrol from here and then sucking air so no fuel in the jets.
I ordered the new O ring (£5.30 from Seamark Nunn) fitted it and off she went like a dream. This was quite hard to spot so if you are having the same problem with an engine this might just be the problem
Pic of the offending part attached and a pdf exploded view of the carb it is part 17 part No 6G1-14984-00. PDF is below the pic
