Tools & Parts
To nail this procedure you may need the following tools, parts, and supplies.
B&S Tune-up Kit
Genuine Briggs & Stratton tune-up kit suitable for Quantum engine family. Picture links to Amazon.com.
Honda Tune-up Kit
Honda tune-up kit includes genuine Honda oil, air filter, and spark plug. Picture links to Amazon.com.
Ratchet Tool Set
Before we can do anything, we’ll need tools. I’ve selected this set as I own some Craftsman tools and while I have worn some out, 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. Set includes spark plug sockets. Picture links to Amazon.com.
Gas & Oil Syphon
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.
Gas Line Clamp
Some small engines will have a gas tap, which is really handy when removing the carburetor, stops gas flowing all over the shop. However most engines won’t have one, these useful clamps simply squeeze the fuel line and prevent a spill while you perform surgery. Picture links to Amazon.com.
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.
Briggs and Stratton refuel can. These guys got it right, I like it a lot, it offers press button control, no fuss no mess and no funnel required. Picture links to Amazon.com.
This tool is used to check both the spark plug and the coil for spark. Sure you can check the spark without the tool, but it’s not as good, the tool is designed to stress the whole ignition system. Picture links to Amazon.com.
I use a DeWalt screw gun (also a drill) in the workshop to speed up the process of removing engine covers, carburetor bolts, Armature bolts, etc. It’s a brushless motor and as tough as nails, I drove over it a few times – still works great! Batteries are interchangeable and so if you have a DeWalt product already you won’t need the battery. Picture links to Amazon.com.
