Having some trouble getting my bike started for awhile now on my 2001 wr-246f.I have had the carb apart many times and cleaned it.Having less than 1k miles on it is pretty clean.A few issues i have with it are. 1)A few of the screws are stripped. 2)The brass hex head thingy that the float goes into is slightly bent from trying to get it out. 3)The air fuel mix screw is stuck in the closed position. I'm thinking of just getting a new carb.Not sure what model number to get.I seen a few used ones on ebay but i'm skeptic to go with something used. Is there a better carb for this bike?If there is what do you think i should go with? Thanks Rob.
