Genuine Dell'orto float to fit the Si 20-20, 24-24 and 26-26 carbs.
The float is an important component that can be overlooked as a problem part, this and the float needle (another problem part), control the flow between the the fuel tank and the carburettor, so if the float is worn or damaged it can take on petrol and will stop the valve closing when the float chamber is full. With the petrol tap left on, this results in a constant flow of petrol into the carburettor, top end and eventually filling your exhaust up until it drips out of the tailpipe! This can also cause problems with starting, flooding and firing.
 Every large scale service should include the replacement of the float and needle.
 
  We only stock genuine Dell'orto needles and floats, we also sell the spring-loaded float needle that compensates for variations in float chambers and therefore reliably offers a more constant fill level.
