- Bingo! That I'll agree with. And the conclusion that I was reaching for. It
- acts like something THERMOSTATICALLY controlled that STICKS sometimes. The
- other replies had discussed something that was occurring CONSTANTLY. One ref.
- was to an exhaust leak that "expansion sealed" and another was a leak in the
- air pump plumbing. Neither quite sounded right, and both were constant. The
- reason that I was skeptical about those ideas (and I do appreciate 'em and
- did check both areas again) was that the noise would have ALWAYS been present
- when the engine was cold (and I admit I may not have been perfectly clear in
- that regard). That condition wasn't true, as the noise isn't always present
- when the engine is cold. Thanks for all the responses. I think it's warm
- enough to work on today, so here goes...
