hi, i started up my sherco 125 today and it starts and idle`s fine with the choke on, but as soon as i turn off the choke the revs drop and the bike cuts out. ive tried turning the air mixture screw on the carb, but if i turn it so it idles well, each rev lasts for about 10 seconds. i did put a little to much oil in with the fuel when i filled it up could this be the problem?
cheers matt.
