Trailmaster tm31x carb

I recently purchased a trailmaster tm31x with the 223 engine. I am working on getting the carb better but still have a bog when snapping throttle. It removed the bowl screws and mixture screw plug. It came with a 40 pilot and 116 main. It seemed lean so went to 42/125. Didn't help much. Went to 45/130 and it seems worse. I am going to try 40/120 and see if I just missed the sweet spot but wondering what others have done. The needle is not adjustable. I would also buy a different carb if needed. Any help would be great. Thanks
