He did mention that the carbs were a little rough but had me bring him a carb cleaner for the gas tank and figured that would solve the issue.
Sorry, he asked you to bring him carb cleaner?
That would have been my first hint.
Anyhow, it does sound like a simple fuel/carb related issue so hopefully it's not an expensive experience for you. Lots of summer left to enjoy, once you get it together and running ride safe.
