Troubleshooting Carburetor Problems in a Riding Lawn Mower
Hi, my name is Bill Parker, and today I'm going to talk to you about carburetor problems; some of the things that causes them and how to fix them. One of the biggest things is introducing contaminants to your fuel whether it'd be water or dirt as well as stale fuel. Stale fuel build a varnish off of the carburetor. So, we've got contaminants in the fuel, we've also got contaminants that come from the air filter. So, we need to run clean fresh fuel, clean air filter and then the last thing is a clean fuel filter. Now, should you have a problem with your carburetor, all those things are at right and you've got contaminants in your carburetor; you brought it in through the air or through the fuel, you're going to have to disassemble it. On a riding mower, you'd have to clamp off the fuel line, disconnect the air cleaner assembly; unbolt the carburetor, disassemble it and spray it with a good commercial grade carburetor cleaner. On a smaller engine it's a little bit different and that the fuel tank and the carburetor all come off as one. Once you've got them both off, you'd disassemble the carburetor from the fuel tank, spray it down and reassemble it. And those are some troubleshooting tips for carburetor related problems.
