Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

It starts fine, always has. But last season I noticed that when it is idling or running under load it idles up and down, the choke does not effect it and the only way that it has a nice steady idle is when it is under a heavy load. There are three other 724s in my neighborhood and none of them sound like this. I have ran out the gas and changed the spark plug to no avail. Also is the friction plate service-able or do I need to have it brought in to the shop? It seems like it only goes forward in the higher settings, reverse is almost no existant.

Thanks!
