I recently purchased a 2005 polaris scrambler 500 high output, and have yet to ride it due to problems. it starts up just fine, but as soon as i take the choke off it dies. second of all, when you push the throtttle in, it bogs down and will die if you dont let it out. however, if you slowly ease the throttle in it will go as normal until a certain point and then bog down and die. anybody have any ideas as to what could be wrong and how i can fix it? Thanks.
