Re: Running backwards
There are reverse rotation 4 stroke engines--but they only run "backwards",they cannot run in either direction...Marine inboard engines often have two V8 engines ,and one is set up with a different camshaft and distributor gear in order to run in the opposite direction of a "normal" one used in a vehicle..A friend had a big boat with two 318 Mopar V8's set up that way..I forget if the starter was a special unit so it would crank "backwards" ,I would think so..
I wonder if anyone ever put one of those marine engines in a car and ended up with three speeds in reverse and only one forward ?...
Some golf carts have 2 cycle engines that will run in either direction,and they have a starter/generator that can spin the engine in either direction ,so they do not need to have a reverse gear,they simple start & run the engine backwards to back up!..
I once had a 2 stroke dirt bike stall out while climbing a steep hill in a sand pit--it started rolling backwards,and the engine started up running backwards,and acted like it was stuck wide open..!..it was a very scary and fast trip to the bottom of the sand pit,and the cycle did a backwards flip when it hit bottom,was lucky I wasn't crushed under it,it flew right over me and landed about ten feet away..
