I bought a 2007 grizzly 80 that has been sitting for 2 years and not running. I have put in a new battery,drained all the gas,cleaned the tank,k&n air filter,spark plug,fuel petcock,fuel filter,fuel line also bought a carburetor rebuild kit with bigger jets (15 for the pilot and 80 for the main. The problem I am having is that the grizzly 80 will idle and run at full throttle but breaks up every where else. I figured it was the needle but the stock one from a grizzly isn’t adjustable. So I went and bought a new needle I have adjusted to all 5 spots on the needle and it still breaks up from 1/4 throttle to about 3/4 throttle. I have let the carburetor soak in carb cleaner for 5 hours and disassembled it removing the jets,air screw,and idle screw. I have also blown out the carburetor with compressed air numerous times. I have the air screw sit at about 11/8 turns out. I am stumped on this bike and have to get it running before Christmas does anyone have any idea what I could be missing.
