If it's an OHV engine, the surging up and down for a few seconds upon cold startup can be common in OHV engines especially with riding mower engines (I know yours is not). If this model has a metal float bowl, the bolt that holds the bowl on is almost always the main jet. If it looks like a type of banjo bolt with some very small cross drilled holes, those holes are the jets and must be completely clean since EPA makes them runs all the engines so lean now. It will actually help if you can open these holes up a thousandth or two. The other type carb has a plastic bowl. Which one do you have?
