I have a 21/48 mower. have problems with running. after a month or so it starts over loading, will start coming & going, spark plugs will sut up. usually i have to change the air filter, some times i can get by with just blowing it out. changed from rcy12 to 14 plugs & that seamed to help a small amount.
when you change air filters you have to use 1 rated for 21hp engine, the ones rated for less wll not last as long. as these filters are expensive, do you know of any cure & cheaper filters? anyone else have this problem & know a cure?
