    My 4.5 10g902 B&S starts fine, but when it runs it revs wide open then almost dies....wide open then almost dies......over and over. I have replaced the spark plug, cleaned the air filter, and put new gas in it. Still the same thing. Any suggestion is welcome!

    Sounds like you need to remove the carb from the tank, Use carb & choke cleaner spray cleaner and clean the fuel pick-up tube screen and make sure the main jet (in the center) is fully open. Replace the diaphragm and you should be back in business.
