Tune it for best power, just rich of max rpm setting.

Verify choke is fully open when running.

Verify throttle plate is fully open at WOT.

Check main jet size in new carb, same size as old? Check for same venturi size also.

Also there could be a fuel filter at the end of the rubber hose in the fuel tank. That can quickly get gobbed up. Also check the spark arrester at the end of the exhaust if it has one. If it is blocked off by carbon it will kill power. Just remove and scrap with a wire brush and reinstall. If you ever get over to harbor freight pick a compression checker. They can always be handy when working on any engine to verify proper compression and rule out any internal problem. The method for checking should start in the fuel tank and work your way to the carb. That is you have verified a good quality spark and air. If you keep you mower outside clean the spark plug connections both on the plug and in the wire.

Parts for mowers are dirt cheap. Always keep handy a replacement air filter, spark plug and fuel filter and spark arrestor if it has one. Changing those out at the begining of the season can be a recipe to cure a lot of head aches. Also fill the tank up at the beginning of the off season to prevent moisture build up and a capful fuel stabilizer as well. If it has been sitting all winter and has not been started, dump the fuel if it wasn't treated or topped off and refill.

Go online with your serial and model number and order your parts by volume. A lot of time you can get a combo set for next to nothing.
