RED-Z06 2,479 #1 Posted December 9, 2021 Back when i ran racing karts we used a device called a Mycron or Digitron gauge that could measure egt, cht, lap times, etc...really good info to have. I found an inexpensive modern option on Amazon that tells you Volts and CHT. pretty simple..the copper ring gives under the spark plug, and 2 leads to the battery. Alternates between the 2 and allows a program to be set that alerts to hi/lo voltage and high temps. I took it out in 72* ambient temps on my C100 and with the deck on in 2nd gear i saw a maximum of 344⁰, dropping to 320⁰ with the deck off and holding there. Upon shutdown it heat soaked to 380⁰ then fell. Im going to 2 sided tape the display on the dash...if i like it ill get or make a more permanent mount. Its useful though, i know...up around 400⁰ you start to lose power and 425⁰ you start to hurt the oil, rings, etc. 4 Share this post Link to post Share on other sites
Moparfanforever 874 #2 Posted December 9, 2021 I still have two of those from kart racing days also. Could be wrong , but I think they were specific to Briggs 5HP ?? Maybe that was just the tach , the lead just zip tied to the plug wire. Have a link ?? Share this post Link to post Share on other sites

If you have a mycron or Digitron they were universal to small engines, wrap the inductive pickup wire around the plug wire, washer under the plug...boom.

squonk 42,588 #6 Posted December 12, 2021 Tach may not work right on a Kohler K series. The Kohler fires once every other revolution off the camshaft as opposed to Briggs and Teckys that fire off the crank. Share this post Link to post Share on other sites
