Hard to start.When running,Will "bog"out when

You may have a fuel issue the cheapest thing to do is a simple fuel filter replacement an old filter can cause backups in the gas line. Also check to make sure your air cleaner assembly is fully hooked up and no hoses or clamps are loose. less air cause these same symptoms.

Did you check fuel filter. if plugged it will starve for fuel. so when you push pedal down it will bog down. especially up hills or grades. lack of power. also it is a good idea to check air filter. if above does not work replace plugs if need be. good-luck !
