I like to play certain music backwards and slaughter chickens on my bike builds and sometimes drink the barley pop.
All ya gotta do on some 2 strokes is a timing change and they will go forwards or backwards it depends on which way is which?! Or which way you want it to go.
simple 2 stroke like model airplane engines will run either direction very happily just so they can cut off a finger. they ae evil.

I think its almost time to go shok----I mean wring a chickens neck. Rufus is poking a stick at the sleeping flyin monkeys and Iron butter fly/ Inna god of divida is playing backwards what kind of mushrooms was that in the salad Snakewoman?
