This is a big shot in the dark. I don't have any experience
with your raven. But I did have a sme 20/2 with a noisy
motor at one point. Turns out I had been putting 2 drops
of oil in it over time vs one drop a year. I thought for
sure it was a bearing going out. Sme sent me some
instructions, 30 min later and a few q tips noise was gone..
