so on my quad it starts and idles perfect. once you start riding it, it makes a little popping noise from the carb at lower rpms like when im driving in 1st 2nd or 3rd gear going slow at lower rpms it will do it, or when im riding and put in the clutch to coast to a stop it will do it sometimes and sometimes it wont. so please let me know what you think it could be id appreciate any help i could get!
