This isn't how it's supposed to sound, right? Options

[Mathman]

Hi folks,

I've just completed my first valve adjustment, and I've put everything back together. However, it doesn't quite sound like it's supposed to. In order to do the valve adjustment, I removed the heat exchangers and muffler. I installed new copper gaskets as well as new muffler gaskets. I'm pretty sure everything is buttoned up the way it should, but it ought to be smoother than it sounds, I think. Do I have an exhaust leak? Poor valve adjustment? Misfiring cylinder? I have enclosed a video that I hope will help y'all help me diagnose.

Okay, I was thinking exhaust leak, but it sounded a lot more pronounced than I'm used to. It had me scared. I did heat treat the copper gaskets, and I stuck them up in the heads using a little bit of grease. I then put each heat exchanger up individually and tightened them up in a cross-pattern. Finally, I hung the muffler, and attached it to the exchangers, using new gaskets. Maybe something did get buggered up in there.

To answer a question, I removed the heat exchangers for a few reasons.
1. It's easier that way.
2. I had another exhaust leak that I am trying to diagnose anyway.
3. Some of us aren't 5'4" and 140 lbs. I am a large man. My hands are about the size of bear paws. I have an 11" hand-span. I simply don't have the room to get both hands, a feeler gauge, a screwdriver, and wrench in there. Why piss myself off fighting all the stuff in the way, if I can just undo a couple of bolts and screws and make my life infinitely easier?

Thanks for the help. I will report back after I get under the car again.
