Questions tagged [small-engine]

Engines used in applications such as lawn mowers, go carts, chain saws, compressors, small pumps, generators, garden tractors, and string trimmers. Frequently hand (pull) started and without an electrical system beyond the spark plug. Technically there is an overlap with motorcycle / scooter engines, but for questions related to motor cycles or scooters those tags are preferred.
