Frequently Asked Questions (FAQs)

1. Do carburetor jets wear out?

Carburetor jets can wear out over time, typically after a few years of use. It is recommended to dismantle and clean the jets about once a year. If the jets do wear out, they can be replaced with new ones of the correct size from a carburetor service kit.

2. What does putting bigger jets in a carburetor do?

When you put bigger jets in a carburetor, it allows a greater amount of fuel to flow into the engine. This can be beneficial if you want to increase the power of your engine or if you are operating your vehicle at high altitudes where more fuel is needed for optimal performance.

3. What are the symptoms of carburetor jetting issues?

Some common symptoms of carburetor jetting issues include bogging on full throttle acceleration, overheating of the engine at high RPM, power flattening quickly at high RPM, pre-ignition sound (pinging) during heavy-load acceleration, and in extreme cases, piston burn-down and seizing. If you experience any of these symptoms, it may indicate a problem with the carburetor jets.
