Pilot System

The polaris snowmobile pilot system’s is designed to meter the fuel at low speed driving and while idling. However, the polaris pilot system’s main function is to supply gasoline at low speed, but it does not provide a constant flow of fuel throughout the entire operating range. 

The gasoline that is supplied to the pilot jet is pulled from the float bowl, it then mixes with air that is regulated by the air screw. It is then supplied to the engine by passing though the pilot outlet. 

The mixture is partially regulated by adjusting the air screw. Fuel mixture becomes rich when the air screw is closed because the amount of air is lessened. The mixture becomes lean when the screw is opened because of the increased amount of air. 

Pilot Jet

When the polaris snowmobile is idling at low speeds, the gasoline supply is metered by the pilot jet. The pilot jet has many air bleed openings that are located on the sides of the pilot jet. These openings help reduce the fuel and creates a mist. Pilot jets are stamped with a number to identify the amount of cc’s that pass though the pilot jet during a 1 min. interval 

Pilot Air Screw

The polaris snowmobile pilot air screw helps to control the gasoline mixture from low speeds to idle. The pilot air screw has a tapered tip which project into the air passage that leads to the snowmobile’s pilot jet air bleeds. If you were to turn the screw out or in, the cross sectional area of the pilot air screw air passage is varied. This in turn varies the air supply and changes the ratio mixture.
