drain the oil and put in fresh
It shouldn't. If you have a dip stick to add oil, you won't also need mixed gas
that is not a good model number for briggs. also you need the type.
Briggs and Stratton does contract anyone to build mowers. The mower manufacturers contract Briggs and Stratton to build their engines (or whatever engine is on the unit). That is why you can have a Briggs and Stratton on most any type of mower. Same is true for Kohler, Tecumseh, etc. Not to say that the engine manufacturers do not build their own type of outdoor power tool but as the question states "snapper mower". Also keep in mind that if you have a snapper mower with a Briggs and Stratton engine and you need warranty work on the engine you need to go to an Authorized Briggs repair facility where as if you have a mower warranty then you need to go to an authorized repair facility for the mower manufacturer.
Yes, most all of the Briggs single cylinder engines are exchangable. You just need to be concerned to make sure that you don't under power your mower. In your case that is not a problem.
