Micrometer measurement to 1/2,000 of an inch.
Total length 200mm. (8 inches). Shaft length 95mm
to 120mm when fully extended. (3 3/4 inches - 4 3/4 inches)
Carburettor Calibration Micrometer (CCM) will help you to accurately
set fuel and air mixtures. Down to 0.0005 of an inch of screw movement.
The CCM allows you to measure the distance you turn a screw in or out
to within 0.0005".
It's a cross between a micrometer and a screwdriver.
Use the CCM for precision ratios with predictable
results. Ideal for carburettor performance, Auto and Competitive
racing, Motocross, Street Bikes, Aircraft etc.
For example if you are adjusting the mixture screw
and you turn it in fully then you can back it out easily to an exact
location, to within 1/2,000th of an inch if you want. You can do
this with other adjustment screws. Take a log of your adjustments so
you know what works for what conditions.
