re: Kill-a watt, Mower engines and noise.

The Kill-a-watt does have a timer. It shows voltage, frequency, amps, watts, power factor, KWH, run time ......and probably more. I have two, but both are being used and I can't get to the units to check. You can cut one in half, putting the socket at one place and the display at another. I used a 10' piece of Cat 5e cable (just happened to have it around) but probably any cable with sufficient (don't remember how many circuits/wires are necessary) number of conductors.

Don't expect a lawn mower engine with a large muffler to be quiet. Once you reduce the exhaust noise, you will discover that much of the noise is just mechanical noise. That is why water cooled engines are so much quieter.
