NQ50 Lock Up

[auraxr]

Anyone have an idea as to what to do about my spree if it sits for very long will lock up with 2 cycle oil in the cylinder and not able to turn over until I remove spark plug and kick it through a few times. This may occur several times (removing plug and kick through) until I block off oil line with pliers til I can get it started. Any help appreciated. Is there some check valve not functioning in oil pump or ?

Have you checked in our "wikispreedia" for this answer ?....I think you are right, the oil pump is failing and i think it is an O-ring.
