i am having issues on gettin my 400 to idle. it started running like this a few weeks ago and after comeing down from high rpms it wouldnt want to stay running so i figured it would be my jetting. well i had asked a question on here awhile back about what to buy jetting wise and i was told two up on the slow jet and two up one the main should be fine well now its still doing the same thing. But now it wants "backfire" through the carb and it just shoots air and straight fuel out. does any one have any idea what i can do to make it fun normal again?
