You have to adjust the secondary side very slow. Especially lowering it. The secondary bowl uses fuel at a much slower rate.

If I'm in the same spot as you, I turn the engine off and drain a little fuel out of the bowl through the fuel screw. Enough so it's below the hole. Then turn the adjusting screw 1/2-3/4 turn down and start it again.

If it's still high, repeat. If it's low, adjust it up very slow and you'll get it.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
