Model 281223BVE, when I have the brake pressed all the way down, it runs and idles fine,then when I start to release the brake,it runs as if it has the choke on,it pops and hardly will run. This happened suddenly,worked one day and not the next.It's like it has a switch,or sensor on the brake system.
