If the engines are mounted to the mower deck in exactly the same way (bolts, mounting holes, etc.), and have similar horsepower, a swap probably would work.
However, if the engine mounting system is different, it would be a BAD idea. Lawn mower engines develop a lot of torque, and you don't want a jury-rigged engine to come loose while running, possibly breaking the blade and sending it slicing into your legs or a neighbor's yard full of children.
Also the dead-man safety interlock might not connect properly. Same for the throttle cable. Same for the propulsion system (if equipped). Same for the mower blade (a jury-rigged blade is even more dangerous than a jury-rigged engine).
Bottom line: If the engine and its fittings are almost identical, then a difference of 1-2 horsepower shouldn't make much difference. Otherwise, don't make the swap.
Briggs and Stratton 30W for 4 cycle engines.
Most lawn mowers have 4-stroke gas engines. Some have 2-cycle, and if you are talking about riding mowers, some even have diesel.
Being that it has crank case oil it would be a 4 Cycle. Engines that you mix oil and gas are 2 cycle.
