The last time I rode the TB was 2 mos ago, it ran fine, but when I went to put it up it was bogging at half throttle. Now it will not start at all and I have removed the airbox, checked spark, checked the fuel filter, and it feels like it has the same compression as always, at least enough to crank. The plug had some fuel on it when I checked spark so I know it is getting fuel. Any help is greatly appreciated.
