New Addition to Fleet and having problems...

[BrianG]

OK, I just got a new addition to my fleet. Weighs exactly 8lbs 1oz, so it's not that heavy. But I just can't seem to get it working right.

It works fine for a little while, but then starts making funny sounds, and even leaks at odd times. When it does this, it smells kinda bad.

Movement is rather sporadic as well.

I'm wondering what I'm doing wrong? Gearing maybe?

Here's a pic of the setup.
