The pole pruner carburetor may be blocked. This often happens when fuel is left in the engine for too long. As time passes, parts of the fuel can evaporate and leave a thick, sticky material behind. This can block the carburetor and stop the pole pruner engine from starting. If you think the carburetor is blocked, try cleaning it with a special cleaner. If it still doesn't work after cleaning, you may need to rebuild or replace the entire carburetor.

2Pole Pruner Spark Arrestor
Most Common Solution
Repair Instructions:
The spark arrestor is a tiny mesh screen that stops sparks from coming out of the engine. It can get blocked up with a carbon buildup called soot. When the arrestor gets clogged with soot, it can prevent the engine from starting. To fix this, take the spark arrestor off and scrub it clean using a wire brush. This should unclog it so it works properly again. If scrubbing doesn't get rid of the clog, the spark arrestor may need to be replaced. Putting in a new spark arrestor will ensure no soot blocks the exhaust again and allow normal starting.

4Pole Pruner Air Filter
Common Solution
Repair Instructions:
The issue could be that the air filter is blocked or dirty. When the air filter gets clogged up, it prevents enough air from getting into the engine. Without enough air, the engine won't be able to burn the fuel properly. This can stop the engine from starting. If your air filter looks dirty or clogged, you should replace it with a new one. Putting in a clean air filter will allow the right amount of air to mix with fuel again. This will help the engine start up normally.

5Pole Pruner Fuel Filter
Common Solution
Repair Instructions:
The problem could be that the fuel filter is blocked. This often happens because old fuel was left in the pole pruner. Over time, some of the chemicals in the fuel can evaporate. This leaves a thick, sticky substance. This sticky material can get stuck in the fuel filter. When the filter gets clogged, it stops the engine from starting properly. If you leave old fuel in the pole pruner, first drain it out of the fuel tank. Then replace the fuel filter. This should allow fresh fuel to flow correctly again so the engine will start up.

- Locate fuel filter - The fuel filter is typically found along the fuel line running from the tank to the carburetor. Note its orientation.
- Pinch fuel line - Use pliers to clamp off the fuel line on both sides of the filter to prevent fuel drainage when detached.
- Remove filter - Slide the fuel line off the old filter's inlet and outlet nipples to remove it.
- Install new filter - Slide the fuel line over the nipples on the new filter, orienting it the same way as the old one.
- Secure clamps - Tighten the clamps on the fuel line around the filter nipples using a screwdriver to prevent leakage.
- Check for leaks - Turn on the fuel valve and check for leaks at the filter connection points before starting.
- Prime the system - Pump the fuel bulb several times to fill the new filter and purge any air from the fuel system.
