With a 2 stroke or 2 cycle engine if the ignition timing is set too close to top dead center it can start to run backwards.
She is a Famous Porn Star know for her "reverse cowgirl spin"
Petrol engine? 4-stroke, no. 2-stroke, some.
A reverse idler gear in a manual transmission. It converts the reverse gears turning direction into the outputshaft to reverse its direction. The transmission can not spin clockwise when the reverse idler is engaged thus it only spins backwards not forward.
Certain airplanes such as the Harrier, can float still, spin and reverse in mid air. This is due to vector thrust engines that have rotating exhausts and louvers that can be pointed downward
When a spinning top is about to stop, the friction between the top and the surface causes it to slow down. This friction can create forces that make the top wobble, leading it to reverse its direction of spin momentarily before coming to a complete stop.
it has alot of torque. the reverse gear is different than first.
go to pennfoster.edu/smallengine it is a site that gives you information about school for repair engine. you can take that class in your home for your private lesson.
crank the motor over and watch which way the fan spins. If your standing in front of the motor and and spins clockwise (to the right) its standard. If it spins counter clockwise(to the left) its reverse.
do you have all forward gears? if yes, you have broken reverse gear (one turning the spin into reverse) in the transmission, if you miss also some forward gears it shifts rough, tranny is to be rebuilt... either way it's expensive fix
If you hit the cue ball below the centre, it will cause a spin which will cause it to go in reverse after hitting a ball.
it it most likely the torque converter this is the link between the engine and transmission if this is damaged the gears will not spin. hope this helps
If you are using PlayStation 2, all you need to do is press square. but to everyone else get then to upgrade the spin slap , and use that to get them to reverse the the move.
