A Word of caution when using these parts for your lawn mower.   Lawn mowers tend to gain high power levels when modified, but the ability of rocks to launch great distances also increases. If you intend to rebuild your lawnmower with these parts, use check your yard for junk when mowing since rocks, wire and other obstacles tend to destroy windshields, paint jobs and can cause bodily injury when hit by the blade.
