I recently bought a 39mm sudco racing carb off ebay(80 Bucks!).The carb came off an 88 250r with a ct 330 cylinder. I think they have some kind off crazy fat needle in it because I just cant get it jetted. My 38mm had a 170 main and I went the whole way to a 190 with the 39mm and it is still way lean.

Does anybody have any experience with Sudco Racing kiehn carbs. Please help!!

 

Anyone
