When a small engine won’t start, the problem can usually be traced back to one of a few common issues—especially if your motor has been sitting unused for a while. These problems include:
- old or stale fuel
- dirty carburetor
- dirty, faulty or disconnected spark plugs
- improper valve clearance
If you still have your repair manual, take a look at the troubleshooting section. Sometimes the problems aren’t obvious, but that doesn’t always mean that major repairs are needed. The solution may be simple and inexpensive to fix.
The most common maintenance needs include checking and changing spark plugs, checking oil levels, cleaning or replacing the air filter, and ensuring that untreated gas is never stored in your outdoor power equipment.
Of course, a number of other issues may be causing your engine problems, including defective coils in the timing system, damaged flywheels, safety switches, cracks and leaks, blockages, and more.
Compression problems could be related to a whole system of valves, pistons, and cylinders which help regulate the amount of air and fuel vapors. Occasionally, testing is needed to determine if there’s a leak or intake/exhaust issue.
