What to do if Jonsered CS 2240 is flooding when engine not running?
If your Jonsered Chainsaw is flooding when the engine is not running, the issue might be a worn needle valve, a needle valve set too high, or a needle valve assembly sticking.
Why is Jonsered CS 2240 idling too rich?
If your Jonsered Chainsaw is idling too rich, consider the following: Adjust the L screw. Check for a worn needle valve, a needle valve set too high, a worn needle valve lever, a leaking control diaphragm/cover plate, or a sticking needle valve assembly.
What causes too much fuel at idling in Jonsered CS 2240 Chainsaw?
If your Jonsered Chainsaw has too much fuel at idling, consider the following: a needle valve set too high, a needle valve assembly sticking, a damaged metering system, a worn needle valve, a leaking control diaphragm/cover plate, or an incorrectly assembled metering system.
Why Jonsered Chainsaw idles when L screw closed?
If your Jonsered Chainsaw idles when the L screw is closed, consider the following: a worn needle valve, a leaking control diaphragm/cover plate, a sticking needle valve assembly, a worn needle valve lever, or a faulty diffuser jet.
Why Jonsered Chainsaw will not “four-stroke”?
If your Jonsered Chainsaw will not “four-stroke”, consider the following: Check for a blocked fuel tank vent or fuel filter, a blocked fuel line, or a loose or damaged fuel hose. Inspect the impulse channel for leaks or blockages. Ensure the cover on the carburettor pump side is secure and the pump diaphragm is in good condition. Look for a leaking air intake hose or loose carburettor mounting bolts. Check if the needle valve is set too low or if there's a leak in the metering system.
