Vernier Prop Control

[Charles67]

If I stay a few days without flying, on the next flight, when I cycle the prop, the control gets stiff half way through the first stroke and gradually improves to become almost normal on the following two strokes. On the following day, the control is normal. But if I wait another 5 or 6 days to go flying, the problem returns.Any idea on what the problem could be? If it is a lubrication problem, what is the recommended lubricant and where should itbe applied?Thanks
