Joe Recard and jmcleod's posts to the thread "914 Thermostat.. does yours have one" both mentioned CHT sensors: A little story.

One day while fooling around on my bench with a stock center console oil temp gauge, I hooked it up to a CHT sensor and applied 12 Volts. The gauge read zero. I applied heat to the sensor with my hot air gun and the guage needle started to go up. When I held the heat on (it is a 1500 watt gun) for awhile, the gauge needle went up to close to full scale. So what does this imply? I think that if you have carbs, you could hook up the stock CHT sensor to an oil temp gauge. You wouldn't know what the temp reading is but, you would have a very inexpensive, relative reading, CHT gauge. Of course, we don't know what the heck the center console oil temp gauge reads either.
