hey guys, after i crank the mower at mid idle, and then while it is running its like my motor revs high, and then low, and then high, and then low, just doing that back and forth. and then when i rev the throttle all the way up to start cutting the grass the mower is fine. it only does this at mid to low throttle speed, whats going on here guys? oh yea, 700 hrs on the mower, 17 hp kawasaki !
