There is a chance I put too much oil in the mix because I filled up on the run. I dumped what I think was 4 oz. (though may have been 6 oz) in the tank after filling it up with just shy of a half gallon. I used SuperS universal 2 cycle engine oil MULTI-MIX. This is different than what I normally use. I rode it maybe 1 mile that night and and maybe 4 the next day, and 3 the day after that and it ran really great. .
I have done this. It is called premix for a reason. If you didn't mix the oil with the gas before putting it in the tank it is likely that the oil made it's way to the carb.
I would take the carb apart and drain the tank. Clean all the parts and reassemble it.
