Carburettor Syringe for Rotax

Syringe for sucking the fuel out of the Dellorto carburetor on, for example, a Rotax Max engine when you're changing a jet.

You connect the syringe to the vent

Angle the carburetor down and suck the fuel out

Change the jets

Angle the carburetor back up and push the fuel back in, so the carburetor is full again and you haven't spilled any fuel, and you don't need to prime fuel to the carburetor.
