Posted August 8, 200915 yr hello everyone, I posted a thread about my 1980 SX400 that ran only on choke, one of the suggestions was that the jets are clogged or dirty gas and gas tank, well I took the carbs out open the float bowl pull out the idle jets and re clean them ( they were not clogged) I checked the petcock filter it is clean there is no rust in the gas tank, as for the idle going up and hanging some where I read that is running lean, I unplugged the caps of the mixture adjust screw and turn out three full turns, put everything back together except the air box, now the bike does not run I got spark, I got fuel coming to the carbs, yet would not run, any ideas?
