So, packing the gear box with Red and Tacky didn't change anything unfortunately. So, I used the old auto mechanic trick of using a screwdriver to touch parts of the engine and put my ear to the handle to see what made the most noise. The motor was very quiet. The top of the gear box was slightly more noisy, but the screw holding the bracket for the top of the gear box was the loudest. I discovered that if I removed the screw and raised the bracket, the noise lessened. I ended up putting 3 flat washers under the screw and that has significantly reduced the screaming noise. The grinding noise is still there, but over all a lot of the noise is gone. There is still a faint screaming noise. Raising the bracket raises the top gear off the lower gear, so not sure if that is the best solution, but the engine seems to run ok. See the videos for shell off and shell on performance. I'm just concerned that raising the top gear will cause damage. Any thoughts ?
