Generator Repair in Farmington, MO
When your generator needs repair, it usually means the power is out, a storm is coming, or a jobsite cannot afford downtime. At Revolution Landscape Equipment & Supply, we help homeowners, property owners, and crews around Farmington, MO get portable and serviceable generator equipment running right before it matters most.
Common Generator Problems and Causes
A generator may seem simple from the outside: add fuel, pull the cord or press the start switch, and expect power. But when a generator sits for months, gets used hard during outages, or is stored with old fuel, several small problems can stack up quickly. That is why a proper diagnosis matters.
Won't Start
Sometimes the engine will not fire at all, or it pops once and sputters. Common causes include stale fuel, a gummed-up carburetor, a fouled spark plug, a dirty air filter, or low-oil shutoff issues.
Starts But No Power Output
The engine may sound like it is running normally, but outlets are dead. This can point to wiring issues, worn brushes, an automatic voltage regulator issue, tripped breakers, or internal head problems.
Low or Fluctuating Voltage
Lights may flicker, tools may not run correctly, or sensitive equipment acts strangely. This can come from engine speed issues, dirty carburetion, overload conditions, or AVR trouble.
Starts Then Dies
It runs for a short time, then quits. This can be caused by a restricted fuel system, clogged fuel cap vent, dirty carburetor, overheating, or a failing ignition component that cuts out when warm.
Overloads and Tripping
A generator may trip because it is being asked to power more than it can safely handle, or because of a failing outlet, damaged cord, or internal fault. We determine if it's a repair or a load-management issue.
Surging or Hunting
If the engine speed rises and falls instead of holding steady, the generator may be fighting poor fuel flow, a dirty carburetor, an air leak, or a governor adjustment problem.
Hard Starting
A generator may need many pulls, long cranking, choke adjustments, or repeated attempts before it runs. Proper service often corrects this before it becomes a full no-start repair.
Why Generators Fail Especially After Sitting
Most generators do not fail while being used every week. They fail because they sit.
The number one reason generators fail after storage is stale fuel gumming the carburetor. Fuel that sits too long can leave varnish and residue inside tiny carburetor passages. When they plug up, the engine may not start, may only run on choke, may surge, or may die under load.
Dirty air filters are another common problem. A clogged air filter can choke the engine, cause rich running, reduce power, and make starting harder.
Old oil can also create trouble. Some generators have a low-oil shutoff system that protects the engine. If the oil is low, old, or diluted with fuel, the generator may refuse to start or may shut down unexpectedly.
Fouled spark plugs are common on generators that have been over-choked or run with old fuel. A worn plug can cause weak spark, hard starting, misfires, and rough running.
Sitting also invites pests, corrosion, dry-rotted rubber parts, dead batteries on electric-start models, cracked fuel lines, and bad connections. A generator that worked fine two years ago may not be ready today simply because time, fuel, and storage conditions have worked against it.
We inspect the engine side and the power-output side so the repair is based on what is actually failing.
Storm-Season & Outage Readiness
The worst time to find out your generator does not work is during a storm, outage, ice event, or extended power failure. A generator that has not been started in months may need more than fresh fuel. It may need cleaning, adjustment, maintenance, or repair before it can carry a real load.
Storm-season readiness should happen before the weather turns bad. If the forecast is already calling for severe weather, repair shops can fill up quickly. A simple generator tune up ahead of time can help you avoid the rush.
Readiness Checklist:
- Start the generator before you need it.
- Let it warm up and listen for surging or sputtering.
- Check the oil level and condition.
- Inspect the air filter and treat fuel with stabilizer.
- Test outlets using a safe, appropriate load.
- Check cords for damage before use.
- Make sure you know what the generator can and cannot power.
- Keep the generator outside, away from doors and vents.
A generator is not something to "hope" will work. It is backup power.
Maintenance We Provide
Good generator maintenance is practical and straightforward. The goal is to make the unit easier to start, more dependable under load, and less likely to fail from preventable issues.
Oil Service
Generators often run for long periods during outages, and small engines work hard under steady load. Clean oil helps protect the engine and reduce wear.
Filter Inspection
A dirty air filter can restrict airflow and cause poor running. A clean filter helps the engine breathe properly and keeps dirt out of internal components.
Spark Plugs
A worn or fouled plug can make a generator hard to start or unreliable. Replacing the plug during service is often a simple way to improve starting.
Fuel Stabilizer
Stabilizer does not fix old fuel that has already gone bad, but it can help protect fresh fuel during storage. We can also talk with you about good fuel habits.
Exercising & Testing
A generator should be started and run periodically, not ignored until the next outage. Running it helps keep parts moving and charges batteries.
Safety Note
Never run a generator indoors, inside a garage, in a basement, in a shed, under a porch, or near open doors and windows. Generators produce carbon monoxide, which can be deadly and cannot be seen or smelled. A generator should be operated outside in a well-ventilated area, positioned safely away from the home. Never backfeed a home through a dryer outlet.
What We Service
Revolution Landscape Equipment & Supply provides generator repair and generator service for many common small-engine generator types used by homeowners, property owners, and work crews.
