This is an original plastic float for the 2-barrel Weber IDA carburetors.
This plastic version was developed for the Spanish versions of the Double Weber carburetors but it is fully exchangeable with the brass version which was made in Italy.
However: the two versions should NOT be mixed within one set-up.
So, please use either ONLY plastic floats or ONLY brass floats on one engine.
Required quantity per carburettor: 1
This is item number 15 in the drawing.
