⚡ Common Problems

Problems We Can Help With

Won’t Start

Stale fuel, blocked jets, dirty plugs and low oil shutdowns are common generator issues.

🎚

Hunting or Surging

A generator that hunts under load may need fuel system cleaning, tuning or load checks.

🛢

Oil & Service Overdue

Generators often sit unused for long periods and need maintenance before reliable use.

🔌

Power Output Issues

Some faults relate to engine speed, load, alternator components or electrical checks.

🔋

Storage Problems

Long storage with fuel can create blocked carburettors and hard starting.

🧯

Safety Concerns

Fuel leaks, damaged leads, loose parts and poor running should be inspected before use.

Basic Output Checks

Generator maintenance before you need it

A generator is usually needed during outages, camping, work or emergency situations — exactly when you do not want it failing. Because many generators spend months in storage, fuel system issues are common. Servicing helps improve the chance of easy starting and stable running when the generator is needed.

Stored generators need special attention

Old fuel can leave varnish in the carburettor and tank, while low oil or dirty filters can affect engine protection. A pre-season service is a smart idea if your generator has not been run in a while.

Honest repair advice

Not every machine is worth repairing. If a repair is likely to cost more than the machine is worth, we will tell you upfront and explain your options before you spend money unnecessarily.
