I-4-C Logger Tach.
Cobra:
Just tell Rod at I-4-C Products what you are going to
use it for and he will see you get the correct RPM readout.
Just like Dub Jett, tell him what plane your going to put
a Jet Fire 50 on and he will set it up with header and pipe
cut a little long and run 8 oz. of fuel through it so it will
start without any hassle.
