So in the process of pulling the carb off my 2000 xr 400 I stripped the screw that hold the throttle cables in place(yes even though the book said not to). Any suggestions on removing it now. Also looking for the best place to buy the rebuild kit. And for jetting. My goal is to be able to ride in 2500-8000 ft elevation. Is it worth rejetting while I have it apart ir stick with stock settings.
