so i have this 2007 rancher that would not start it would crank and not fire.. i sprayed some starting fluid and it would fire right up. I took the carb apart and soaked it and cleaned it then put it back on and it idles perfectly now but there is a problem when i try to give it throttle. It falls on its face and then you have to play with the throttle to get it to rev up and then it looks like its spraying raw fuel back out of the carb... anyone have a clue whether its the idle mixture screw or something else?? im beggin for some help
