  If your Ducar Engine does not start, there might be several reasons. First, check if the battery is empty and charge it if necessary. Ensure the fuel shut-off valve is open. Verify that the controls are in the correct position for starting. Make sure there is enough fuel in the tank. If the engine was stored for a long time, drain the old fuel and replace it with fresh fuel. Inspect the spark plug for defects or fouling and adjust the gap or replace it. If the spark plug is wet with fuel, dry it and try starting the engine with the throttle in the FAST position. If all else fails, there may be a clogged fuel system, carburettor malfunction, ignition malfunction, or jammed valve, which may require replacing or repairing defective parts.

  Reduced power in your Ducar Engine can be caused by several factors. Start by checking the filter inserts and clean or replace them if they are clogged. Ensure that there is enough fuel in the tank. If the engine was stored without proper fuel treatment, drain the old fuel from the tank and carburettor and refill with fresh fuel. Finally, a clogged fuel system, carburettor malfunction, ignition malfunction, or jammed valve could also be the cause. In such cases, replace or repair the defective parts.

What to do if Ducar DVO150 is running roughly?

  Andrea RiceAug 29, 2025
  If your Ducar Engine is running roughly, it could be due to a defective spark plug, which should be replaced. Another potential cause is an incorrect gap between the electrodes; adjust the distance between the electrodes to 0.7 - 0.8 mm. Clogged filter inserts can also lead to rough running, so clean or replace them.
