How to clean and maintain your Briggs and Stratton 675 Series Carburetor

简介

This guide takes a little more work than some of the other lawn mower replacements. You first remove the air filter, and then go behind it to remove and clean the carburetor tank. You will use a socket wrench with a 5/16" and ½" hex bit and a prying tool. Before you get started, you may want to purchase an O-ring if your lawn mower is old, as the O-ring in the carburetor tank may be worn. Cleaning the carburetor may get messy, so do not attempt it inside.

    • Once the bolt is removed from the bottom of the carburetor tank, gently pry open the tank with a metal prying spudger until it pops off. If you do not have a spudger, a flathead screwdriver will work.

    • Completely remove the tank so you can clean it or replace it.

I just performed a carb tank cleaning based on your DIY and it took less than 30 minutes! The best part of the cleaning was an immediate start of my mower on the first pull. Thanks

Nice guide. My mower was only running on choke, any other throttle setting and it would die. A quick online search indicated dirty carburetor and subsequently I found your guide. Gave everything a good clean and voila! Good as new.

Slide clamp on fuel line back and pull fuel line off carb. plug line with old pen/pencil

Remove two nuts holding carb onto engine. Remove nut holding engine choke arm on top of carb. Then remove two springs and one carb adjust metal arm. Note places of attachment

spray cleaner in all brass jets, use fine wire to clean out all orifices, clean bowl attachment nut. Spray cleaner in to choke area and tip upside down and spray under the bowl needle.

drain old gas out of tank and alternatively add a in line fuel filter as well a new air filter.

clean or repl spark plug

yes, this is a better guide for cleaning. the other should be called "how to inspect your carb O-ring"
