Back in the the 1950s I ran a decrepit two stroke motorcycle. On one occasion it started but did not sound right. On letting in the clutch it began to move backwards, which explained the abnormal exhaust note! This ability of the two stroke to run in either rotation was used on early Messerschmitt bubble cars, which had two contact breakers to allow the engine to be run in either direction, eliminating the need for a reverse gear.
