– Optical Tachometer
An adaptor is made by welding a compressor air fitting to the
base of an old spark plug. The adaptor is screwed into the spark
plug hole of a head and connected to the leak-down tester to
check the condition of the cylinder assembly.
An accurate optical tachometer. Reads directly from reflective
strips fitted to the propeller and is used whenever an accurate
check of RPM is required. Will usually read propeller RPM in
sunlight without reflective strips.
