Looks to me like its one of those tiny 125cc start and go two stroke motors. They don;t have a clutch....just push the kart and say good luck. Might run into problems trying to use it....but good luck rebuilding it. If you stick on a small battery and a motor to the axle ~250W...you could use it like a golf kart...mash the pedal and it starts.

... but does anybody know where it is from?...

Sure.. it's from italy ;) (no honestly, it's from italy)

100cc .. some iame;
the head is a Komet of sorts.. K30 or such.. K71 or 77 perhaps
the crankcase looks more to be a Sirio 51TT.. I might be wrong on that though
could also be a K80-K88 crankcase.. hard to tell (for me at least)
Anyways it's for sure a late 70ies (to mid 80s perhaps) iame engine;
most likely a Komet series

And yes it's a rotary valve engine,
nearly impossible (at least highly impractical monetary wise) to install a clutch
it's direct drive or high dollars let's say.

the carb goes to the right side of the engine, just mm above the tiny sprocket that sits on the crank;
no room for a directly attached clutch without removing the carb (which is of course not possible)

I can't tell for sure but it appears you have the option to mount a reed valve to the (still sealed) pump base (the flat part on the crank case)
IDK if there are matching valves and if it makes sense whatsoever to try.
You would need to contact a iame professional to know for sure.

appears to be in good shape..
amazingly so even given it's old and from a scrap yard.
I bet you can easily sell it for ~ two brand new OOTB predators (200++ bucks ?)
vintage racers like getting their hands on good engines like that for restoration projects.

great engine btw..
if you find a maintenance manual, go ahead.. restore that and see how 100cc make every modded predator cry ;)

thx to both of you,

just think i need to get a new piston 50,7mm
dont know if that is worn alot? :D,

but anywhay, i am crossing my fingers, not everyday you get to restore somthing older than your self, so if you have any more ideers of to what motor it is, where to get a piston and gaskets, it would be really helpfull, and i would post the restorations images along the ride.

just find a iame dealer in your area, and ask for support.
nearly all iame cylinders and pistons from any rotary valve fit any other rotary valve engine
So chances are you can slap on whatever is available.

Or on the internet contact iame
info@iamekarting.com
send them two scaled down images (cylinder/head and crankcase.. not much bigger 120kb each)
and no links (spam filters don't like links and the unknown adress of yours doesn't help with that)
ask if they can help you with a maintenance/overhaul manual to restore it
and for a parts source in your area.

you will need to replace the bearings as well,
this thing has some serious oopmhp packed,
and it revs at high speeds (assume no less than 13k rpm... I'd say maybe 16k max)
you do not want this thing spitting metal your way..
so better buy bearings now than regretting it later ;)

PS here's an overhaul manual for a more recent reedjet aircooled iame:
http://iameusaeast.com/content/KA100 Overhaul Manual.pdf
it doesn't help much but gives you a good idea about the overall task at hand ;)

PPS:
oh the uk online dealer has historic parts:
http://www.iame.co.uk/products/historic/
100cc 50 series pistons is what you're looking for..
