I have a blaster that would not idle until I got a carb rebuild kit had someone install and was good for 2 days now back to not idling and carb is leaking gas now
Cheap eBay carb kits! They suck, get a new Yamaha kit and be sure to check your float for gas inside floats . Hold it under in a glass of gas . If it bubbles replace it! Then install kit and new float. Set the float height level. Do not push down on the resilent ( rubber tipped) needle! Reinstall carb simple.Peace
