If you have the sp460 roller self propelled it should only idle this is to prevent the mower running away from you! it cuts at a nice gentle speed with little effort keep it running sweet i've had mine 7+ years. Great ps if it starts to play up ie hunting replace diaphragm,spark plug,air filter,both govener springs & clean eveything. mine was sounding iffy? now running like a sewing machine. Ta
