DT 55 idle and low rpm misfire

[lukeb99]

I have a 1995 dt 55 that has a misfire at low rpm and at idle, above about 1300 rpm it smooths out and runs fine . any ideas? just installed new plugs thought maybe a carb issue

Could be an ignition problem, might try cleaning carbs first.

cleaned the carbs

Muddy stuff in carbs plugging High Speed jets. I get 5500 RPM now.

just now got around to cleaning the carbs. got it started and still have the same issue bottom cylinder seems to be the strongest. top two cylinders dont change rpm when pulling plug wire. although engine still runs with bottom cyl. wire pulled. i also swapped the ign. coil from top to bottom cyl. any help would be greatly appreciated
