How do you adjust the idle speed on a handheld gas leaf blower ?

Thanks... that's cool. So, you just point that "arrow' at the spark plug? How far away can you be before you
are out of range?

Well, the manufacturer says between 4 and 15 inches, but I found that I had to be pretty close to get a reading, 4 inches or less. Maybe mine has a weak battery.

Oh, forgot to ask. Does it work on diesel engines? If so, where do you point it?

No, it only works on gas engines. They do make a tach that will work on diesel engines, but it is not wireless.
