False Warning Horns

Here's a new one for ya.

Monday I take a friend back to Norfolk (ORF) from Greenville, SC (GMU). It seems like the front prop is hunting a little bit once I hit about 5000' and I have to synch the props frequently. Acted a little bit like a mag, but a mag check at altitude had a reasonable drop and return with the check. And I just had both prop governors overhauled last year at annual.

So anyway . . . I drop him off and head from ORF to Charleston Exec (JZI). As I'm climbing out of 2500' I smell something like burning rubber for about 5-10 seconds (that's how I know my altitude, because I started looking immediately). But . . . the gauges didn't blip, move, or otherwise budge, no power outage, the smell stopped, no smoke, and everything seemed happy (except me). I cautiously continued on (always knowing where "nearest" was) and completed the flight without event.

I get on the ground at JZI and check everything out, and everything appears to be fine.

Yesterday, I'm on my way from JZI to GMU in solid IMC. I'm cruising comfortabley at 160 kt with a tail wind and a smile on my face. Suddenly, a warning horn goes off intermittently while I'm at 6000'. I can't tell if its the stall horn or my gear horn, but I instantly check my airspeed, AI, DG vacuum system, and then cross check against my Garmin 295. As expected, straight and level with no loss of speed. I check my gear, it's retracted, and I've got the amber light still glowing strong.

The warning horn stops after about 10 seconds . . . and never goes off again. I get towards GMU and am on the ILS, and am expecting the worst from my gear, still scratching my head about the horn. Gear comes down perfect on first cycle without event, I land and everything seems fine.

The questions are:

What was the smell out of ORF and what's the deal with the false, intermittent horn?

Anyone had anything like this before?
