Default Need carb advice on lt230 that has been bored

Lt230 just bored to 250. Ordered a carb kit with larger main jets. I've tried a 122 and a 150 main jets. I also have a 175 jet and the factory 115. Both jets make the quad starve for fuel at WOT. I've tried moving the needle clip from lean to rich without success. It is popping at WOT. Air screw is set at 2 3/8 turns. Any idea what the correct jet size would be?

In the stock carb with a dg pipe i ran a 125 main and a 25 pilot with a .040 overbore. and had no issues even when running stock exhaust.
