ive disconnected the battery while its running before too, we know cars run without a battery but what we want to know is will it START without a battery?

Clutch start.

Starter's don't run on plankton..

I think the mythbuster question is, if you do this clutch start, will the residual magnetism in the alternator coil be enough to produce a voltage for the ignition coil?

it would be a damn big hill to get it to spin the thing fast enough to excite

my mini with a generator can do it though, but its the same fault with teh reg that flattens the battery that lets me get away with it

wouldnt the residual magnetism in the rotor generate a small voltage in the stator, which will feed back into the rotor to generate a greater magnetic field and greater and greater and greater voltage out of the stator? So the smallest amount of residual magnetic flux/webbers will be enough to get the alternator producing a voltage. This is the same principal as pull start motors isnt it?

you think too much, go get an alternator and stick a meter on the back and spin that thing as hard as you can and see what happens

cant be assed, easier to make a post about it.

No - pull start motors use magneto ignitions - with permanent magnets.

what about my starter generator on my LJ20????

Do I need a battey??? and if I put the terminals on wrong can I make it run in the oppsote direction since its a two stroke?????

yes.
