Product Overview
Slika 1: The Toro Pilot Jet, Part # 81-1030. This image displays the small, brass-colored pilot jet, a critical component for regulating fuel mixture in carburetors.
The pilot jet is a precision-engineered component responsible for controlling the fuel flow at idle and low-speed engine operation.

Operativni principi
The pilot jet is a fixed orifice that meters fuel into the engine during idle and low-throttle conditions. It works in conjunction with the pilot air screw to create the correct air-fuel mixture for smooth engine operation when the throttle plate is nearly closed. A clean and correctly sized pilot jet ensures that the engine receives the precise amount of fuel needed for starting and maintaining a steady idle without stalling or running too rich/lean.
Održavanje
Regular inspection and cleaning of the pilot jet are essential for maintaining engine performance. Fuel contaminants or varnish buildup can clog the small orifice of the pilot jet, leading to poor idle, hard starting, or engine stalling.
- inspekcija: Periodically inspect the pilot jet for any signs of clogging, corrosion, or damage. This typically involves removing the carburetor bowl as described in the installation section.
- čišćenje: If the pilot jet appears clogged, carefully clean it using a fine wire or a carburetor cleaning spray. Ensure the orifice is completely clear. Nemoj use abrasive tools that could enlarge or damage the jet's opening.
- Zamjena: If the pilot jet is corroded, damaged, or cannot be thoroughly cleaned, it should be replaced with a new genuine Toro Pilot Jet (Part # 81-1030).
Rješavanje problema
If you experience issues related to engine idle or low-speed operation, the pilot jet may be a contributing factor. Below are common symptoms and potential solutions:
| Simptom | Mogući uzrok | Rješenje |
|---|---|---|
| Engine stalls at idle | Clogged pilot jet, incorrect idle mixture | Clean or replace pilot jet. Adjust pilot air screw (if applicable, refer to equipment manual). |
| Hard starting (cold or warm) | Partially clogged pilot jet | Clean or replace pilot jet. |
| Rough idle or surging | Partially clogged pilot jet, air leak | Clean or replace pilot jet. Check for carburetor gasket leaks. |
