Toro 22056 idle when blade brake on
I just picked up[ a used Toro 20056 Super Recycler. It runs great except when I let go of the handle and the blade brake engages, the idle is lower and not as smooth. It sputters and pops to a slight degree. As soon as I start mowing again with the blade brake disengaged, it idles up and runs very smooth. Is this normal? I have already cleaned the carb and intake, changes the oil and put fresh gas in. The plug and air filter are brand new. Any ideas?
