RPM spike

I noticed that my 16 hp vanguard has been loping or fluctuating engine speed lately and recently had a much higher than usual rpm spike when I left off on the trigger gun. Just wondering if its getting ready to blow or what. Any one else ever have anything similiar?

Thanks

Other possible things to check are: Fuel fiter may be getting plugged, Main jet on Briggs become plugged easily. Pilot jet might be plugged. The stock fuel filter on briggs is terrible and will let small amounts of dirt and debris pass by and slowly build up in the float bowl covering the all important main jet. This will cause hunting also. Like Wizard said it sounds more like a govenor problem though.
