Dellorto 17.5mm carb without the auto choke installed
17.5mm is larger than stock carbs and gives you that added air and fuel when upgrading exhaust or cylinder kit
Carb bolts on a ET2 two stroke Vespa scooter and many other scooters using Spigot mount for install which means it does not bolt on to the manifold but simply slides in rubber manifold boot.
Great carb for many scooters
comes without electric choke which can be used without as long as you are in warm climate
