I have a husqvarna riding lawn mower with a Briggs and stratton Intek 24 hp twin V OHV. The engine seems to be missing on one cylinder. I have replaced the ingnition coils and spark plugs. I have inspected the wiring to the ingnition coils but it still is missing. what else can I check?

Check that you have a spark at the plug. You can use a plug tester or hold a plug against the engine. (Hold the cap not the plug!). Check you have fuel to the cylinder. After trying to start is the faulty cylinder spark plug wet, does it smell of fuel? If not check the valve clearances on that cylinder. If all that is ok, check the ignition timing.

Hi, check the valve clearances, regards Phil.
