Your Briggs and Stratton carburetor is an integral part of your small engine, so it’s important to keep it running smoothly for the overall health of your lawn mower, snow blower, and other outdoor power equipment. In this article, we’ll give you tips on carburetor maintenance and repair to keep your small engine healthy – so that you can use your power equipment worry-free!

Before starting any carburetor maintenance or repair work, make sure to consult the Briggs & Stratton operator's manual for the machine you will be working on and follow all safety precautions.

Carburetor Maintenance: Cleaning & Adjusting Small Engine Carburetors

Performing regular carburetor maintenance is a great way to save yourself money, headaches, and hassle down the road.

Most carburetor problems are caused by a variety of blockages from thinks like dirt, varnish, and gasoline deposits. It's easy for the main fuel jet to become blocked, but luckily it's a pretty easy fix. Regular carburetor maintenance will help you avoid problems in the future.

You can clean the main fuel jet (located in your carburetor's fuel bowl nut) with carburetor cleaner and compressed air to blow out loosened debris. Carburetor cleaner dissolves deposits in your carburetor and choke, and consequently can reduce your need for maintenance, repair, and downtime, while improve starting for all 2-cycle and 4-cycle engines.

Carburetor Maintenance and Repair

After cleaning the carburetor, another key step for some float-type carburetors is adjusting the idle speed and mixture. Full instructions for Adjusting a Briggs and Stratton Carburetor are available in our FAQ section.

Performing regular small engine maintenance and tune-ups are another way to maintain your carburetor and prevent engine problems. Briggs & Stratton engine tune--up kits contain new air filters, spark plugs, oil, and easy step-by-step instructions. You can find engine tune-up kits in the Briggs & Stratton official parts store online.
