    Dumb question of the day - Can you jump start a manual transmission car with a dead battery by pushing it backwards and popping the clutch when in reverse?

    I know it can be done the normal way.

    I would think so. It might be a bigger strain on your transmission, but it should be the same basic principal.

    The gear ratio might be a bit too low. I remember push starting cars in 2nd or higher.

    The engine will run backwards.

    (OK, probably not.)

    It used to happen on occasion on our two-stroke dirt bikes when we were kids. Kick it over. It starts but runs really rough and the tach is broke, all of a sudden. Give it a lot of gas, because it's running really rough, and let out the clutch. It jumps backwards, goes "Buh"!", and stalls after you hit your face on the crossbar.

    I used to do mine in 1st. 2nd may be better, but it works in first.

    Lol, no. A car's engine doesn't change direction when you're in reverse, that's all handled in the transmission. This would only happen, theoretically, if you pushed the car backwards, then let out the clutch... with the transmission in one of the forward gears. The engine not starting would likely be of little concern at this point.

    The sheer hilarity of seeing the guy pushing, suddenly face-planting on your hood would leave you completely incapable of driving.

    :supergrin:

    :rofl: :rofl: :rofl:

    Awesome.

    Just be sure to mash the clutch and hold it in during your laughing fit to keep it from stalling.

    My dad said he had it happen a few times, I never had a smoker so I've never seen it. I did have the engine on my RC plane start backwards once. Hit the throttle and the plane moved backwards, took me by surprise at first :supergrin:

    My brother and I would push our CJ-2A out of the carport in and start it reverse all the time as the battery always seemed low and the ground wasn't that good.

    I would say V8s would be harder to start and some vehicles have some pretty high ratio reverses.

    There also may be some kind of electrical lock out on some of the newer vehicles.

    The Cox engines did it often enough. Fire up the Sandblaster, drop it on the ground, and it blasts sand backwards. Laugh so hard you can't breathe and try to make it happen again. You can't.

    It can be done. It will be harder than pushing the car forward and letting the clutch out in first gear.

    That is how I have always done it.

    Yes, it's possible.

    As far as two-strokes are concerned, some spin backwards for reverse. It's common on newer snowmobiles. Hit a button and the engine just about dies and then fires back up spinning the opposite direction.

    Yes you can start one in reverse.

    ETA: Motorcycles will start in reverse as well. Providing you can find the -R- on shift pedal.

    I used to do it all the time with my VW. I've done it a few times in my truck too.

    If anything I think it's a bit easier in reverse as there's more torque to turn over the engine.
