Replacing the chemical injection valve in your Excel gas pressure washer

  • Wear work gloves to protect your hands.
  • Disconnect the sparkplug wire from the spark plug.
  • If detergent is in the detergent reservoir, clamp the chemical injection hose near the chemical injection valve. Use an open-end wrench to turn the chemical injection valve counter-clockwise and remove it.
  • Install the O-ring on the new chemical injection valve. Lubricate the O-ring with silicone lubricant. Thread the new chemical injection valve into the pump and tighten. Reconnect the chemical injection hose. Release the clamp from the chemical injection hose, if used.
  • Reconnect the spark plug wire.

What to do when the engine won't start on your Excel gas pressure washer

When the engine doesn't start, first make sure the rocker switch that controls the engine is in the On position. Next, check the fuel; the engine won't start if the engine is out of fuel or if the fuel is stale or contaminated with water. Replace the fuel in the gas tank if the fuel is older than 3 months.

Bad fuel can contaminate the carburetor. Clean or replace the carburetor if it's gummed up from using stale fuel.

The engine may also need a good tune-up so it will start easily. A tune-up includes changing the oil, changing the spark plug, replacing the air filter, checking the ignition system and adjusting the throttle and choke controls.

A bad recoil starter can prevent the engine from starting. If the engine doesn't spin when you pull the starter rope, you'll likely need to replace the recoil starter.
