darn jetting

I'm running a 138 main with the air box lid on, nothing else in the jetting is changed just the main. I'm getting a stumble at 1/2 to 3/4 throttle. Anybody have some advice on what to adjust????

Thank you sand neck. You may have just saved my carburators life because I have been trying to get the jetting right for a while now!

If the problem doesn't cease, try going in size bigger (richer) on your pilot jet. The pilot handles just about everything between 1/2 and 0 throttle. I had the same problem after i rebuilt my lt230
