Carburettor pressure gauge

That's an excellent precision. For the client, it is crucial to understand that Pressiometer is the measuring tool, but that is the combination of spring and lever which physically creates the trigger.

Here is the update of the sheet with this indispensable technical explanation.

High Precision Carburettor Pressiometer – Ref: ADPVG

The ADPVG Pressiometer is the ultimate diagnostic tool for karting. It allows you to see precisely when your carburetor "opens the valves" to power the engine. Without this tool, it is impossible to know whether your tarage spring is actually doing its job.

Characteristics Technical:

• Reference: ADPVG

• Direct Reading: High visibility gauge (Bar / PSI).

• Use: Measurement of trigger pressure (Pop-Off) and the holding pressure (tightness).

• Stability: Anodized aluminum base for stable use on the set of stands.

The Magickart Commitment: Accuracy is measured, it does not guess. Magickart guarantees you the lowest price in France and Italy on the metrology tool Tillotson!

Michel's Council (Magickart): Who does the trigger?

"Many pilots think that it is only the spring that decides everything. My expert advice: the trigger is the result of a fight between the gas pressure (which you send with the pressiometer) and the force of the Spring (R33) transmitted by the Levier (R20).

How does it work?

1. The Spring (R33) pushes the lever to keep the point closed.

2. The pressure rises in the carburetor (the pressiometer needle that climbs).

3. When the pressure becomes stronger than the spring, it lifts the pointer: It's the trigger!

Products that work together:

• Spring R33 (26g to 46g): It is he who gives the main resistance. The heavier the trigger, the higher the pressure.

• Pointer lever (R20): Its height is crucial! If it is too high or too low, it changes the lever effect on the spring and distorts your trigger, even with a new spring.

• Le Pointeau (R18): If it sticks because of a dried essence, the trigger will be erratic.

A little pro secret: If you fail to obtain the required pressure despite the right spring, check the alignment of your lever (R20) with the carbide body. The ADPVG pressiometer will tell you immediately if your installation is compliant or if there is a mechanical bone. At Magickart, we don't sell you just a tool, we give you the method of champions!"

Tuto: Mastering Pop Off with ADPVG

1. Situation: Connect the pressure gauge to the gas inlet.

2. Pressure rise: Pump slowly. The needle goes up because the spring R33 Keep the pointer closed via the lever.

3. The breaking point: At one point, the needle drops at once (often with a small 'click'). It's the trigger. 4. Interpretation: * If it triggers too early (e.g. 0.50 bar instead of 0.80): Your spring is too soft or your lever is too high.

   • If it triggers too late: Your spring is too hard or your point is "gommé".

4. Adjustment: Change the spring (see our range from 26g to 46g) and repeat the test until you get the perfect value for your engine.
