Default King Quad 300 Gas Issue

98 KQ 300 was flooding out carb and wouldn't take throttle, so i cleaned carb, and So everything is good now that I bypassed the vaccum on the petcock and went strictly "prime" Except for now it's not getting enough to run past half throttle....up until half throttle it runs perfect, idles perfect, no more running rich or black smoke load up.....do I need to get a plain petcock that's not vaccum operated.....thanks in advance
I have a clear fuel filter installed, and it's not even filling it up

pull line off petcock check flow if petcock if has some blockage the delivery isnt enough an atv burns more fuel than carb receiving just trying to make sure before you go back into carb thats, all

Here a photo of the fuel pump up under the left front fender mounted on left corner of frame this is why I wanted you to check the fuel delivery with remote tank if pump isnt pumping enough fuel to petcock the carb bowl isnt full enough causing the engine to use more fuel than then the bowl has causing it to stumble or die and If you bypass the pump atv could die on hills because tank and carb is at the same level
