My mini moto goes 4 about 100meters ??

sounds like fuel starvation if it restarts after a few seconds then this is the most likely cause. Clean or replace the petrol filter. if its ok then take the carbuerreter apart there will probabley be a bit of dirt in the pipe which lets fuel into the float bowl. the fuel can't fill the float bowl up as fast as you are using it when the throttle is wide open.

this could be your carb try taking it off a cleaning it with compressed air. and check your mixture make sure it is not to rich as could be putting the spark put
