My pressure washer is leaking gas as soon as I filled the tank. Every season I expect not to be able to start my Troy-Bilt pressure washer because of issues as a result of old gas and corrosion of the carburetor. I was prepared to make the fix that I do every season, which is to clean the ports in the bowl nut. All I wanted to do was clean my driveway with a new pressure washer surface cleaner I purchased.
My Decision to Repair
As you can see in the video it was leaking by the carburetor. My guess is that the o-ring gasket around the bowl or the small gasket around the bowl nut failed. Rather than investigate that issue I decided to purchase a replacement carburetor. I had already removed the original carburetor in preparation for this.
Time to Replace the Carburetor
The carburetor was easy to remove with the exception of the bolts. I could not get a socket on the bolt but I was able to use a Torx bit to remove the carburetor bolts. One suggestion I have is to take several photos of the carburetor at various angles so you can visually double-check where all linkages and springs connect.

Once I installed the carburetor and put a little gas in the tank it started right up after a few pull starts. You’ll see in this video Pressure Washing is so Easy with this Surface Cleaner that I successfully cleaned my driveway with the new pressure washer surface cleaner.
Savings and Empowerment
Other than my time to diagnose and replace the carburetor I only incurred the cost of a replacement carburetor. A repair bill by a professional small engine repair shop might be $100 or more depending upon your region. I thank my neighbor Joe who helped me build up my confidence enough to tackle small engine repair. Once you understand the inner workings of the small engine it is a rewarding process to fix your own equipment. If you are not comfortable at least you have an appreciation for what a professional would endure to resolve your issue.
