Installing a engine on a snapper rear engine mower

It is not difficult. The boggest thing is getting the linkages, fuel lines if there was an external tank, wiring and belt rounting the same as it was before you remvoed the old engine. Usually there are only 4 engine mounting bolts and the the engine comes free. Once you have the 4 bolts out you can losen the belt / drive assy and lift the belt free. You will have to transfer any engine output pulleys or drive connections to the new engine. Just note the distance on onthe output shaft from the old engine to the new one.

The biggest problem most people have is they forget to service the new engine with oil then pull the engine through to fill the oil filter (on larger engines) to pre-oil the engine. What happens is the oil level initally drops and the oil level sensor kills the spark.

It really is more simple than most people would think. It is all a matter of the time it takes to align the engine, control linkages, belts or engine outputs.
