Made in China, the 24 mm carbs fit a variety of Scooters and ATV’s with 150 cc motors or GY6 clones. These are from a closed Scooter store and each have some parts missing, so it looks like they could not be sold as complete. You get both carbs (2) with free priority shipping. Great deal if you play with these small engines. selling for parts only. One is Sheng Wey, one is Kaisheng.
