K&B .61 crank stiff

Postby dwdl21 » Thu Sep 09, 2010 6:31 am

I have a nib .61 #6525 and when I tighten down the prop nut the crank gets real stiff, when I loosen the the prop nut the crank is still stiff and I have to tap the crank to get it to loosen up, anyone have any ideas?
thank you

The bearing are probably not seated or the prop driver is rubbing on the front of the case. Check the prop driver first. NIB does not give me history on the engine. If you did not buy it from a hobby shop you don't know if it was taken apart and reassembled.
