Main jet -DELLORTO- 5mm, 50 micron
The jet plays an extremely important role in carburetor adjustment.

If it is too small, the mixture is lean, the engine stalls at full load. In this case, the piston and cylinder overheat due to lack of fuel and oil. A sign of a lean mixture is a white electrode on the spark plug.

If it is too large, the mixture is rich, the engine tries to burn a large amount of fuel, for which it has no capacity. Signs of a rich mixture are more exhaust gases and cracking during acceleration.

For this, it is extremely important to find the ideal medium.

To determine the correct jet, it is advisable to start from large to small. Once you find such a jet, install a smaller one until the engine stops "choking" at full load.

The following carburetors use a 5mm jet as a secondary:
PHBH, PHBL, VHSA, VHSB, VHSC
The following carburetors use a 5mm jet as a primary:
PHBD, PHBG, SHA, SHBC
