the after run oil coming out from the front bearing is normal mate so dont worry at all ive had new motors do this ! All it is the after run is over flown in your motor.just remember before you start it take the glow plug out then give it a few turns over with you starter box! and watch out for your eyes!
then put the plug in fill ya tank then prime put the glow on then you should be away and going. Besides its a good thing any way atleast you know the after run is doing its job properly!
