2010 250 no start issue
After riding for several months and several hundred miles on my new (to me) 2010 250, I am experiencing a no start issue. The problem is not with the battery, as it tries to turn over. I don't know if it's the spark plugs or not, but I doubt that both would just completely fail at the same time. If I open the choke and open the throttle slightly while trying to start it, it might turn over...however it immediately dies after releasing the throttle. Fuel also dumps out from what I think is the carb overflow tube. What my research has turned up so far is that the float or floats are probably stuck or sunk, and that cleaning the carbs should help resolve the issue. I've already tried mechanically agitating the float bowl, but that hasn't worked.
Just to clarify: I pulled the air filter and observed that air box while attempting to start. The box that houses the air filter is what floods with fuel and then drains the fuel out after the bike dies.
I just want to verify that cleaning the carbs is the correct course of action before taking this on. Please also note, this is my first bike. Although I'm somewhat mechanically inclined, my knowledge on how a motorcycle works is VERY limited.
