I have a 2000 Yamaha Blaster, it has been sitting for roughly 6 months or so, and it will not run unless the choke is out, it runs fine when the choke is out, but as soon as i press in the choke it seems to be cut off from the fuel... What can i do to fix this? I have already cleaned out the carb but that didnt seem to do it... any suggestions? thanks
