Are you looking to rebuild the carburetor on your Suzuki Quadrunner? This video will show you everything you need to know to get the job done right—from selecting the right parts to completing the rebuild. Follow along as we walk you through the process of rebuilding the carburetor on your Suzuki Quadrunner!
To start this process, the plastics need to be removed in order to begin to reach the fasteners to get to the carburetor. With the seat removed and the gas tank cover out of the way, the bolts to the gas tank need to be removed, as well as the lines to the carburetor.
The carburetor throttle cable and choke can begin to be removed from the carburetor, taking care to not strip the threads of the plastic nut that holds the choke in place. Once all the lines and cables are free, loosen the carburetor from the intake manifold and work it out of the frame. Once removed it’s time for disassembly.
Taking the carburetor apart is fairly simple, the fuel bowl is removed, jets are removed, the idle mixture screw is removed taking care to note how many threads it is from bottoming out. I found a whisker of junk in the needle and seat, which is where my sticking float issue was occurring. The vacuum diaphragm on the top needs to be carefully removed as they are difficult to find replacements for. I used an ultrasonic cleaner to clean the carburetor and then blew compressed air through all of the passages to ensure they are clear. Using a carb kit from a reputable source, you can replace all of the gaskets, and hard parts that are needed. Reassemble the carb and It’s time to head back to the ATV.
Back at the ATV, and getting it mostly in place allows you to manipulate it to get the choke and throttle cables into place. Put the carb back in place on the intake manifold and tighten it down. Replace the vacuum lines after inspecting them for cracks and overall condition. Replace the gas tank and hook it up to the carburetor. I would highly recommend testing the ATV before putting all of the plastics back on, it makes it easier to get to the carburetor for tuning and in the event that something needs to be addressed, like a leak. Once you’re satisfied with how it’s running, put the plastics back on and enjoy!
