i just got an xr200 1998, and it will start sometimes and runs if you keep the throttle back. and it dont stay running, it also leaks, out of the carborator, what could be wrong? could the float in the bowl be bad?? and be overflowing and floodin it out? im not really sure ive worked on it pretty much 3 days straight and i have no idea what else the problem could be? please email me and let me know if you think you know whats wrong. plase and thanks.
