i did the rings on my 2003 grizzly 660 ( I’ve done rings before multiple times) and I also cleaned the carb while apart and after putting back together it runs like crap idles fine starts fine but about half throttle cuts out and dies . I have gone back through the carb 3 times all jets are clean , fuel screw is 2 1/2 turns out and diaphragm in fine , throttle clip position is in the middle . One thing I did notice is that if I cover the intake half way or more (with box and filter) it runs way better. Any help wold be great thanks in advance
