Questions:

How long had it been running when you did the video?

Did you use any starting *aid* to get it going (such as ether)?

Does the knock/rattle match changes in RPMs, both in frequency and volume?

Can you please do another video, which includes:

1. Steady camera shots, don't move around the whole time
2. At least one closer shot of where you can hear the noise the loudest
3. No background talking
4. LIGHT (I know you are concerned with the sound, but it helps to be able to SEE what is going on too)....
