      If your LONCIN Engine won't start, several factors could be the cause. First, check if the battery is discharged and recharge it if necessary. Ensure the fuel valve is in the ON position. If the engine is cold, make sure the choke is CLOSED; if warm, leave it OPEN. Verify the engine switch is set to ON and that you have sufficient fuel. If the fuel is old or bad, drain the tank and carburetor, then refuel with fresh gasoline. Inspect the spark plugs for faults, fouling, or incorrect gaps; gap or replace them as needed. If the spark plugs are wet, dry and reinstall them, then start the engine with the throttle lever in the FAST position. For more complex issues like a clogged fuel filter, carburetor malfunction, or valve problems, consider replacing or repairing the faulty components.

      If your LONCIN Engine lacks power, start by checking the filter elements for clogs and clean or replace them as needed. Ensure that the engine has enough fuel by refueling if necessary. If the fuel is old or of poor quality, drain the fuel tank and carburetor, and then refuel with fresh gasoline. In case of a clogged fuel filter, carburetor malfunction, ignition malfunction, or a stuck valve, replace or repair the faulty components.

      If the fuel in your LONCIN Engine is bad, it could be due to the engine being stored without treating or draining the gasoline, or refuelling with bad gasoline. The solution is to drain the fuel tank and carburetor, then refuel with fresh gasoline.
