2000 blaster need help!

Sounds like an easy fix. Clean your carb, clean your reeds, and clean your airfilter. I would just clean everything first, could be like others said a broken reed, but hopefully not.
 
Sounds like a stuck choke, or reeds. But like mentioned earlier, i would check and clean the Carb, Air Filter, and Reeds. If none of that is the problem, then i would look at the TORS. I removed mine and have never had a fuel/oil/bogging problem since. Its very easy to do..
 
TORS would have been the very first thing I woulda tried and probably could have saved you a lot of work. Then if that did not work then I would have delved into cleaning the carb.
 
can someone please explain to me what the tors is....i was having the same problem with my laster and i called a local shop and they told me that the parking break sensor was sticking.....they told me to take the front hood plastic off and disconect a conector consisting of a black a yellow and black and a yellow wire....i did this and it took care of the problem
 
TORS is Throttle Over Ride Sensor I believe. It only takes about 5 minutes to remove it for good. But ya, it sounds like TORS or Parking Brake sensor.
