The tools and repair kit on this page will help you fix your classic Briggs and Stratton engine from the dreaded surging. I have listed a few other tools that would make life easier for you but they’re not strictly necessary. Check out the surging video here.
Cleaning the fueling system in most cases fixes the problem. Check this post out, “Carburetor cleaning”, but sometimes you’ll need to bite the bullet and fit a new carburetor. Check out the “Carburetor cleaning video” here.

Stabil Fuel Stabilizer
Mix this with the gas when winterizing your small engine. Gas isn’t what it used to be, it goes stale, in some cases after just one month. Bad gas causes gumming and that’s a carburetor killer. A stabilizer will save you money and stress in the long run. Picture links to Amazon.com. Check out “Adding stabilizer video” here.
When cleaning your carburetor you’ll need this stuff. Gumming is a sticky substance that’s hard to shift. The carb cleaner will remove it, however, if your carb is really bad, save yourself some work, go ahead and buy a new carburetor. Picture links to Amazon.com.
You’ll find this tool really useful if you need to drain the gas tank, and you will if the gas is stale. The siphon will remove it without fuss or mess and it can be used for extracting the oil too. Picture links to Amazon.com.
You’ll find these nylon brushes super useful when it comes time to clean those tiny passageways of the carburetor and jet. Use these in conjunction with the WD Carb cleaner. Picture links to Amazon.com.
Before we can do anything, we’ll need tools. I’ve selected this set as I own some Craftsman tools and while I have broken them, they did do a lot of work. So I expect this set will last the occasional user quite a long time. This set carries both metric and standard sockets and that’s important because some mowers will have both types of fastener sizes. Picture links to Amazon.com.
B&S Manifold Pipe
The manifold crossover pipes are made from plastic and as they get older they can become brittle. A cracked pipe will cause the engine to surge also. There are a few different types, so check the mounting face before ordering. Picture links to Amazon.com. Check out the surging video page, second video down shows how to fit the manifold pipe.
