If your Craftsman M260 lawn mower won’t start, you are not alone. This model has been sold for years, and owners searching for a craftsman m260 lawn mower won’t start fix tend to run into the same handful of problems: stale fuel, a fouled spark plug, a clogged air filter, or a safety interlock that is not engaged. This review looks at the M260 as a product, explains what it does well, where it falls short, and walks through the no-start issues that come up most often, so you can decide whether to repair it or move on. It is a research-based review drawn from manufacturer specifications and common owner reports, not a hands-on test.
Product Overview
The Craftsman M260 is a walk-behind, gas-powered push mower built around a single-cylinder, four-stroke engine in the 140cc to 160cc class. It uses a rotary blade, a rear-bagger-ready discharge design on some configurations, and a self-propelled drive system on the models sold with that option. The mower is aimed at homeowners with a standard suburban lot who want a dependable, mid-range machine rather than a commercial-grade unit.
Most of the M260’s reputation rests on its engine and its simple, serviceable design. Owners generally report that the mower is easy to work on, parts are widely available through Sears Parts Direct and third-party suppliers, and the deck is straightforward to clean. Starting problems, however, are one of the more commonly mentioned complaints, and they are almost always traceable to fuel, spark, or air delivery rather than a fundamental design fault.

Pros & Cons
Pros
- Simple, air-cooled engine design that most home mechanics can service with basic hand tools.
- Replacement parts such as spark plugs, air filters, carburetor kits and blades are widely stocked.
- Steel deck holds up reasonably well to typical residential use when kept clean and rust-free.
- Pull-start design means no battery to maintain, which suits people who store the mower seasonally.
- Available in push and self-propelled configurations, giving buyers some flexibility.
Cons
- Starting issues are among the more frequently reported complaints, particularly after storage periods.
- The carburetor is sensitive to ethanol-blended fuel that sits for more than a month or two.
- Recoil starting requires more effort than electric start, which can be a barrier for some users.
- Cutting quality depends heavily on regular blade sharpening and correct deck height adjustment.
- Not designed for large lots or heavy, continuous commercial use.
Performance Analysis
On paper, the M260 is a capable mower for a lawn up to roughly a quarter acre, assuming regular maintenance. The engine displacement is adequate for a 21-inch-class deck in typical grass conditions, and the single-blade rotary design produces a clean cut when the blade is sharp. Owners who keep up with oil changes and air filter cleaning often report several seasons of reliable service.
The weak point, based on owner feedback patterns, is the fuel system. Modern gasoline containing ethanol can absorb moisture and degrade over time, leaving varnish and gum in the carburetor jets. A mower that ran well in June may refuse to start in April if the fuel was left in the tank over winter. This is less a flaw in the M260 specifically than a reality of small-engine ownership, but the M260’s carburetor design gives little tolerance for neglect.
Starting also depends on spark. A worn or fouled spark plug, or a spark plug wire or boot that has come loose, will produce a weak or absent spark. Owners frequently report that a fresh plug solves the problem outright. Air delivery matters too: a clogged paper or foam air filter starves the engine of air, causing hard starting and rough running even after the mower fires.
Self-propelled models add a layer of complexity. The drive system and safety bar can interrupt the starting circuit if the operator is not in position, so a mower that cranks but never fires may simply have its safety switch in the wrong state. Consult the owner’s manual for the correct start sequence, which typically involves setting the choke, engaging the primer, and holding the bail or bar as specified.
Who Should Buy This Product?
The M260 suits homeowners with a small to medium lawn who are comfortable with basic maintenance. If you are willing to drain or stabilize fuel before storage, change oil on schedule, and keep the air filter clean, the mower can serve you well for years. It is also a reasonable choice if you value a pull-start engine that does not depend on a battery.
You should skip the M260 if you have a large property that requires hours of mowing per session, if you want a no-hassle electric start, or if you are unwilling to perform seasonal storage steps. Buyers with limited mechanical comfort may find that a newer electric or battery-powered design requires less upkeep.

Buying Guide
If you are shopping for a mower and considering the M260 family, start by measuring your lawn. As a general planning guide, a push mower with a 21-inch deck works well for lots up to about a quarter acre, while larger properties often justify a self-propelled model or a riding mower. Self-Propelled Lawn Mower Selection Guide covers the trade-offs in more detail.
Next, think about starting convenience. Pull-start engines are simpler and more durable in the long run, but they require more effort. Electric-start versions reduce strain but add battery maintenance. Push vs Self-Propelled Lawn Mowers explains how drive style affects effort and control.
Before committing to any gas mower, consider your storage habits. If the mower will sit for several months, plan to add a fuel stabilizer or run the carburetor dry. Lawn Mower Winter Storage lists the steps.

FAQ
Why won’t my Craftsman M260 start after sitting all winter?
The most common cause is stale fuel that has gummed up the carburetor jets. Drain or replace the fuel, clean the carburetor if needed, and install a fresh spark plug. How to Fix a Lawn Mower That Won't Start After Winter walks through the full process.
How do I know if the spark plug is the problem?
Remove the plug, inspect the electrode for heavy carbon or oil fouling, and check the gap against the manual. Reconnect it, ground the threads against the engine, and pull the cord while watching for a spark. A weak or absent spark points to the plug, the boot, or the ignition system.
Can a dirty air filter stop the mower from starting?
It can. A severely clogged filter restricts airflow and makes starting difficult, even when the fuel and spark are fine. Remove the filter, tap out loose debris, and clean or replace it according to the manual.
Should I use ethanol-free gasoline?
Ethanol-free fuel is often recommended for small engines because it degrades more slowly. Check your owner’s manual for the manufacturer’s specific guidance on fuel type and ethanol content.
What is the correct starting procedure for a self-propelled model?
Follow the sequence in your owner’s manual. Typically, you set the choke, prime the carburetor, and hold the safety bar or bail as directed while pulling the cord. Skipping a step, particularly the safety bar, can prevent the engine from firing.
When is it time to stop repairing and replace the mower?
If the engine has low compression, persistent smoke, or repeated carburetor failures despite cleaning, the repair cost may exceed the value of the machine. A new mower may be the better long-term choice.
Is it safe to work on the carburetor myself?
Basic cleaning and plug replacement are manageable for most owners with care. Work in a ventilated area away from ignition sources, disconnect the spark plug wire before any service, and drain fuel first. If you are unsure, consult a qualified small-engine repair technician.
Final Verdict
The Craftsman M260 is a practical, serviceable mower that makes sense for homeowners with modest lawns who are willing to maintain it. Most no-start problems are caused by fuel degradation, fouled spark plugs, or clogged air filters, and all of them are fixable with basic care. If you are weighing a purchase, be realistic about storage and upkeep. For a mower that is easy to live with, you may also want to compare the options above.
