Is your Honda GCV 160 mower surging, sputtering or refusing to start after long-term storage? Don’t worry. This guide will walk you through the Honda GCV160 carburetor diagram and show you how to clean your mower carburetor.
Understanding Honda Carburetor Diagram
Before you grab your wrench, let’s make sure you understand exactly how this tiny carburetor works in your engine. Knowing the Honda carburetor diagram will make the cleaning process easier.
Honda GCV160 Carburetor Diagram Explained
Here is the diagram for the Honda GCV 160 mower carburetor for you. Let’s get to know each key component part that we’ll be handling.
- Pilot Jet: This is the most crucial part for fixing a surging idle. It works to regulate the fuel flow at low speeds. Even a tiny speck of dirt here will cause the engine to sputter.
- Idle Speed Screw: A spring-loaded screw that adjusts how fast the engine runs when it is not under load
- Idle Mixture Screw: This screw controls the air-fuel ratio at idle. If your mower starts but dies immediately, this might need cleaning or adjustment
- Throttle Shaft & Plate: These components rotate to control the amount of air entering the carburetor, directly affecting engine speed
- Copper Tubing: This is the fuel inlet where the gas line connects to deliver fuel from the tank into the carburetor bowl.
How to Clean Honda GCV160 Carburetor?
Since we’ve gone through the functions of each key component in the carburetor, let’s settle down to the Honda carburetor cleaning.
Tools and Suppliers
Before we start, gather the following necessary tools and materials:
- 10mm Wrench or Socket
- Flathead Screwdriver
- Brake Cleaner
- Air Compressor
- Mallet (Optional).
Step-by-Step Guide on Carburetor Cleaning
The cleaning procedure generally involves the following three sections:
Access the Carburetor
- Disconnect the spark plug wire for safety purposes
- Take off the air cleaner cover and filter element
- Blow the dirt and grass out of the air filter
- Use a wrench to take the bolts off and undo the whole carb assembly
- Pay close attention to the gaskets’ orientation and order
- Turn off the fuel valve and disconnect the fuel line
- Remove the governor linkage and the small spring
Perform a Deep Clean
- Unscrew the 10mm bolt at the bottom of the carburetor
- Tap with a mallet if the carburetor bowl is stuck
- Unscrew the pilot jet and the internal tube with a flathead screwdriver
- Spray brake cleaner through all holes
- Use compressed air to ensure every passage is spotless
Reassemble and Reinstall
- Put the long side of the internal tube back in first, then the jet. Do not over-tighten the jet
- Reinstall the gaskets, the auto-choke mechanism, and the air box in the correct sequence (Gasket -> Auto Choke -> Gasket -> Carburetor -> Gasket -> Air Box)
- Reconnect the linkage and spring before mounting the carburetor back onto the engine
- Connect the breather tube and the fuel line for the final check
- Turn the fuel back on and start the engine
- Check if it should run smoothly without any surging
How to Reconnect Carburetor Linkage with Diagram?
While cleaning the internal jets is straightforward, like many DIYers, you may find the mechanical connections on top of the carburetor to be the most challenging part of the job. You may encounter the linkage coming off and have no idea how to connect it again after the carburetor cleaning. So, it’s better to reconnect the governor system before mounting the carburetor to avoid frustration.
