I installed a new mikuni carb on my 2011 450 grizzly EPS . It started right up but is idling high . I adjusted the idle screw no help checked throttle and choke cable seem to be operating fine.I do have a question about the choke i think there where two plungers in the carb I looked on line and it looked like only one goes in so I only installed one . When I choke it the idle slows down a little . Do I need to adjust the pilot screw if so where is it . Please help weathers getting nice cant ride the way its running.
