Alejandro,

That's not uncommon, particularly with newer engines... Its a result of using full-compliment bearings and its not a problem if the shaft comes free again with relatively little torque. I've seen it on a variety of turbines from production units right down to home built engines... Once turning again, the balls should spread out nicely in the races and the rotational drag will be greatly reduced. As the motor gets some time on it, this shouldn't happen nearly as often. If the engine ever runs 'dry' from a clogged lubrication orifice, that's another story... The 1300R shouldn't have that problem though, since it's got a 'last chance' fuel filter under the front cover of the engine.

On the other hand, if the shaft is frozen in place and very difficult to get moving again on any turbine, obviously you should consult the manufacturer or service centre.
