What to do if Jonsered CS 2145 Chainsaw engine stalls when throttle released?
If your Jonsered Chainsaw engine stalls when the throttle is released, try the following: Adjust the L screw, adjust the H screw. Also, check for a faulty pump diaphragm, a needle valve set too high, a sticking needle valve assembly, or faulty diffuser jets.
Why Jonsered CS 2145 Chainsaw has low power?
If your Jonsered Chainsaw is experiencing low power, consider these potential solutions: Adjust the H screw, check for a blocked fuel tank vent or fuel filter. Inspect the impulse channel for leaks or blockages. Ensure the cover on the carburettor pump side is secure, and examine the pump diaphragm for faults. Also, check the air filter for blockages, the needle valve assembly for sticking, and the metering system for leaks or incorrect assembly. Look for loose diaphragm rivets or holes in the diaphragm, and check for a leaking control diaphragm or cover plate.
What to do if Jonsered CS 2145 will not idle?
If your Jonsered Chainsaw will not idle, try these solutions: Adjust the L screw. Check for a leaking air intake hose or loose carburettor mounting bolts. Inspect the fuel hose for looseness or faults and ensure the fuel filter isn't blocked and the fuel line isn't blocked. Also, ensure the fuel tank vent is not blocked. Check the throttle valve pivot, pushrod, and return spring for stiffness, sticking, or defects. Look for a bent throttle stop and a faulty diffuser jet.
Why Jonsered CS 2145 idling uneven?
If your Jonsered Chainsaw is idling unevenly, consider the following solutions: Check for a blocked fuel filter or fuel line, a leaking air intake hose, or loose carburettor mounting bolts. Inspect the throttle valve pivot, screw, and valve for wear or looseness. Also, check for a sticking needle valve assembly, leaks in the metering system, a worn metering system centre knob, or a hole in the diaphragm. Finally, look for a leaking control diaphragm/cover plate or a crankcase leak.
Why Jonsered CS 2145 idling too rich?
If your Jonsered Chainsaw is idling too rich, consider these potential solutions: Adjust the L screw, check for a worn needle valve or one that is set too high. Also, inspect for a worn needle valve lever, a leaking control diaphragm/cover plate, or a needle valve assembly that is sticking.
Why Jonsered CS 2145 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, or a blocked fuel line. Inspect for a loose or damaged fuel hose, a leaking or blocked impulse channel, or a loose cover on the carburettor pump side. Check for a faulty pump diaphragm, a leaking air intake hose, or loose carburettor mounting bolts. Also, check if the needle valve is set too low, or if there's a leak in the metering system, or if the metering unit is incorrectly assembled. Finally, inspect for a loose diaphragm rivet, a hole in the diaphragm, or a leaking control diaphragm/cover plate.
