Engine oil on prop blades front & rear

[Jhogan0101]

Today i put some duct tape where the prop flange meets the crankshaft.
After doing that i did a run up and no more oil on the prop.
I do remember when seating the new inner mounting ring (a1633-3) id did seem a little small but it is the correct part number. Also the correct thickness, i measured before installing (100 micron)
Next step is to remove both props and replace the ring again. Fingers crossed.
