i just recently bought a 2000 yamaha blaster yfs 200. I need to know how to adjust the carb, i have it 3 1/2 screws out and its running good. but i dont want to blow the rings. I also need to know whats good 2-stroke mixing oil to use.
 
Well since you don't mention WHICH screw you have out 3.5 turns, we can only guess it is the air/fuel mix screw. The proper technic is usually to start at about 2.5 turns out, start the machine and turn it in till it just about stalls, then turn it out till it just about stalls and then put it at about the middle.

As for 2 stroke oil, Walmart, Kmart, and all autoparts stores sell it. As do lawn mower shops. Make sure it says 2 stroke oil on the bottle.
