Repace the screws on the bottom of your Carburetor with these Stainless Steel  Allen bolts and washers. If you think this is a good idea, you  have  probably already  opened the bowl of your carburetor and realized  that  every trime you do it, the screw heads strip. Don't wait  until it's time to figure out how to get  the screw out once the head is completely stripped. Replace the  screws with these  and make it  easy every time. Stainless  steel.

Fit Vespa, Piaggio, Aprilia, Honda, Kymco, Yamaha, Genuine, Sym and other Scooters  with a Keihin carburetor.
