I have a carb I’m wondering if I should get rid and start from scratch. A couple things going on. First is whoever I go fast for however long and begin to slow down the four wheeler wants to stall. It will not idle on its own. I have to keep giving it gas to keep it running. The choke won’t stay out without me holding it out. The idle screw has been stripped and the place where that idle screw was is now filled in with some black stuff. The tors wiring is cut on one end and on the end disconnected. Here are pictures. Thanks for any help!
