Measurement Conversion Chart Piston Wash / Spark Plug Reading
Changing temperature, barometer, altitude, and fuel
supply are just a few of the factors that can affect the day
to day performance of your engine. That is why using
Exhaust Gas Temperatures (EGT) are important for
maintaining optimum performance. There are two
methods for helping you determine what the EGTs are for
your machine. Piston wash and the coloring of your spark
plug. The piston wash is by far the most valuable tool in
concluding EGTs, with the spark plug color running a
distant second. Use the illustrations below to help
establish the EGTs for your machine.
Once the proper jetting is established, you can reference
the EGT gauge for your baseline numbers. Then, if there
is a rise or fall of 25 degrees, you must jet accordingly to
return your EGTs to the baseline numbers.
