Mikuni Gas Carb ?'s

[9603banshee]

I'm switching from gas TM 35 Mikuni's to gas TM 38's on my 350 cub...My jetting on the 35's is, 330 mains on the 2nd clip from top....Where do I start with the mains on the 38's w/ the same clip position?? Any help is very much appreciated...

I would start with the same main and needle position as used on the 35's. I dont know if the 2 carbs have an interchangeable needle jet orafice (dump tube) but you want to make sure you are in the right range on the needle jet orafice or you wont be able to tune the needle enough to make it run right with changing the clip position.
