Runs fine at open throttle, but when blade engaged, or going uphill, or any kind of load, begins to backfire intermittently. Also has a slight surge. Ideas?

Another possibility is that it is not getting sufficient fuel? Check your fuel filter and fuel pump (if applicable). Make sure that you are getting a good flow of fuel to the carburetor. If you can't find anything wrong, you will have to pull the carb and clean it.
