RE: Quick ??...Which Way Should Engine Shaft Turn?
it will run backwards too. I do it all the time for fun. runs like crap tho. snowmobiles have spark so when you hit rer(sonthin electronic reverse) it shuts the engine off for a seccont then starts back up spinning backwards, trully amazing if you ask me, that it can start moving in the opposete direction with no starter moter. well any way the spark is changed electronicly to make it spark at a diffrent time.
unlike a nitro where it depends sololy on port timing, where a snomobile has reeds. or pistion port design.
any ways try it backwards for fun, just make shure it wont hurt your clutch at all.
