Carb Question

[Gas Stu]

Hi gents, I have an 02 Ec 250. just changed jets from 38 pilot to 40, and 168 main to 170. Its runs way better but now battles to start when cold.Once it fires up it idles very high. What could it be. Air screw is almost 2 turns. Starts first kick when warm.....whats up here

It sounds lean on the bottom , try taking the air screw in about a turn while it's idling & see if it slows the idle.
