Fouling plugs can happen for a number of reasons;
* low rpm operation for extended periods, plugs don't get hot enough to burn of oil residue
* too much fuel, too little air (jetted too rich, or air intake restricted (very dirty air filter), air density (e.g.. cold air / low altitude = higher density = leaner running, warmer air = richer running
* wrong plugs (too cold)

Hi dont forget the rh crank seal sucking all the gearbox oil into the engine, always a suprizing source of fouled plugs. Link
