Main sprinkler included 06413 – for Dell-Orto VHSH carburettor / VHSB

Main sprinkler type 06413 compatible with carburetors Dell-Orto VHSH and VHSB, widely used on KZ karting engines and other 2 stroke motors.

The proposed sprinklers are and manually controlled to ensure the actual value of the gas passage. Piping consists of measuring precisely the diameter of the sprinkler in order to obtain a much more reliable and accurate carburetor setting than the original value indicated by the manufacturer.

Important:
The number of the sprinkler is entered on the plastic bag of packaging.
He Do not rely on the number engraved on the sprinkler, because it corresponds to the manufacturer ' s origin value and not to the actual measured value.

1 What is a "peg" / "pied"?

One Spider got it is a sprinkler whose the actual diameter was controlled with a precision pin (a calibrated stem). This tip allows measure exactly the diameter of the nozzle hole, which determines the amount of gasoline that passes through the carburettor.

In karting competition, this operation is important because the numbers engraved on the sprinklers do not always match the actual diameter.

2 Why do we get karting sprinklers?

The sprinklers are usually by flow and not by exact diameter. Two sprinklers with the same number may have a slight difference in gas flow.

Piping thus allows:

• to obtain a much more precise carburetor setting

• to have the true value of the sprinkler

• improve engine performance and reliability

• avoid an engine too poor or too rich

3 Discrepancies between marked splicers and loaded splicers

In practice, we often observe a gap of approximately 7 to 12 points between the number on the sprinkler and its actual value measured with a pin.

Common example:

• marked sprinkler 130

• actual diameter measured 137 - 138

This is why many KZ preparers and pilots use Spillers got to obtain more reliable and accurate adjustment.

4 How you get a sprinkler

Control is done with a box of jugs calibrated to one hundredth of a millimetre.
We insert the pin into the sprinkler until we find the one that fits perfectly into the hole, which makes it possible to determine the exact diameter of the sprinkler.

5 Why is it widely used in KZ

The KZ engines and 2 strokes are very sensitive to carburation adjustment. A poorly calibrated nozzle can cause:

• loss of power

• engine overheating

• motor clamping

The Spider got it thus allows to get precise carburetor settingadapted the runway and weather conditions.

Characteristics:

• Type: Main sprinkler

• Reference: 06413

• Compatible Dell-Orto VHSH / VHSB

• Spilled and controlled

• Real value indicated on the bag

• Ideal for precise settings in karting competition

Ideal product for drivers wishing optimize the performance and reliability of their karting engine.
