1. Connect up the carbtune
2. Turn on the engine and take the readings
|
Everyone knows how the mercury Carbtune works.
There is a column of mercury in a tube. The tube is connected to the engine.
The vacuum in the engine pulls the mercury up the tube. You take readings
off the scale.
It's a good idea until you drop it, turn it upside down or try to transport
it.

3. Adjust the carburettors to get the readings
as even as possible
4. To between two red lines, and that's it!
|
Except you have a column of stainless steel rising and falling. No
chance of that leaking!
The ground and polished stainless steel columns float smoothly through guides that have been machined to fit them. The guide acts like a seal and the column moves through it vertically. This is contained inside a clear plastic tube which gets connected to the engine. The vacuum from the engine draws the stainless steel column up through the guide. |
Simple! Just like the mercury manometer except it's smaller, there are
no liquids to spill and as the Carbtune II is made from high impact plastics
and metal it is much more robust.
