Clogged or dirty air filter.
Flooded engine due to excessive priming or repeated unsuccessful start attempts.
Solutions:
Drain and replace fuel with fresh, high-octane fuel mixed at the correct 50:1 ratio.
Ensure the correct fuel/oil mixture and only use high-quality two-stroke oil (API-TC, JASO-FD, ISO-L-EGD).
Remove spark plug, inspect for fouling, clean or replace if necessary, and check the gap setting.
Clean or replace the air filter as specified in the owner's manual.
If the engine is flooded, hold the throttle wide open and pull the starter repeatedly to clear excess fuel.
Low water pressure:
Possible Causes:
Loose or leaking hose connections.
Clogged intake strainer restricting water flow.
Worn or damaged impeller reducing pressure.
Engine running at insufficient RPMs, not delivering full power.
Solutions:
Inspect all hose connections for leaks, tighten as needed, and replace damaged hoses.
Check the intake strainer for debris or blockages and clean thoroughly.
Inspect impeller for wear, cracks, or damage; replace if necessary.
Ensure the throttle is fully open and engine is running at manufacturer-recommended RPMs.
Overheating:
Possible Causes:
Blocked cooling fins preventing heat dissipation.
Improper fuel mixture leading to inefficient combustion.
Extended operation at high RPMs without cooldown periods.
Solutions:
Inspect and clean engine cooling fins, removing dirt, debris, or blockages.
Ensure correct fuel-to-oil ratio to prevent overheating and premature engine wear.
Allow regular cooldown periods during extended use to prevent engine overheating.
Leaks:
Possible Causes:
Worn or deteriorated pump seals and gaskets.
Loose hose fittings or cracked hoses.
Solutions:
Inspect all seals and gaskets for wear, cracks, or deterioration; replace as needed.
Check all hose fittings for tightness and ensure no cracks or leaks in hoses.

Each wildfire season is a stark reminder of how unpredictable and devastating these natural disasters can be. For homeowners, the importance of being prepared cannot be overstated. Families often have minutes—or even seconds—to react. Having a well-thought-out 'Go Bag' ready can mean the difference between safety and chaos during a wildfire evacuation.
This guide is your definitive, step-by-step resource to creating an emergency 'Go Bag' specifically designed for wildfire scenarios. You'll learn what to pack, how to organize it, and how to stay ready for the unexpected.
Why Wildfire Emergency Preparedness Matters
Wildfires are increasingly frequent and destructive, fueled by rising temperatures, longer fire seasons, and encroaching urban development. These fires spread rapidly and unpredictably, often leaving little time for homeowners to evacuate safely.
Fires don't wait for you to pack or decide what’s needed. That’s why having a pre-packed emergency 'Go Bag' ensures you're ready to leave at a moment’s notice, equipped with essential supplies to keep your family safe.
Understanding the Unique Challenges of Wildfire Preparedness
Unlike other emergencies, wildfires require quick, decisive action. Here are a few key challenges homeowners face when preparing for wildfires:
Unpredictable Behavior: Wildfires can change direction or intensity suddenly, meaning you may have only minutes to evacuate.
Smoke and Air Quality: Apart from the flames, smoke inhalation can pose a significant health hazard, especially for children, the elderly, or those with pre-existing conditions.
Evacuation Logistics: Families need a clear, practiced plan to evacuate efficiently without scrambling for supplies.
Now that we understand the stakes, let's prepare.
How to Create a 'Go Bag' for Wildfire Emergencies
Your 'Go Bag' is your lifeline—a collection of items to sustain and protect you during an evacuation. It should be easy to carry, well-organized, and tailored to your family’s needs. Follow these steps to build yours effectively.
Step 1: Choose the Right Bag
Start by selecting a sturdy, easy-to-carry bag such as a backpack or duffel bag. Water-resistant bags with multiple compartments are ideal for keeping your items safe and organized.
Step 2: Pack the Essentials
Organize your 'Go Bag' by category to ensure every survival need is met. Here's what to include:
1. Survival Essentials
Bottled water (at least 1 gallon per person per day)
Non-perishable food items like energy bars and canned goods
Multi-tool or Swiss Army knife
Emergency blanket
Flashlight with extra batteries
2. Communication Tools
Fully charged portable phone chargers or power banks
Battery-operated or hand-crank emergency radio
A written list of emergency contacts
3. Personal Documents
Copies of IDs for all family members
Proof of home ownership or rental agreements
Insurance documents
Medical records
4. First Aid Kit
Bandages, gauze, and antiseptic wipes
Adhesive tape and scissors
Pain relievers
Prescription medications (if applicable)
5. Hygiene and Comfort Items
Face masks to protect against smoke inhalation
Travel-sized toiletries (toothbrush, toothpaste, wet wipes)
Hand sanitizer
A spare change of clothes
6. Items for Children, Pets, and Special Needs
Diapers, formula, or baby food if needed
Pet food, leash, and any necessary medications
Additional supplies for elderly or disabled family members
Step 3: Pack Strategically
Heavier items like water should be packed closer to your back for ease of carrying. Use plastic bags or watertight containers for documents or electronics to protect them from moisture.
Step 4: Don’t Forget Your Vehicle Emergency Kit
Prepare a second kit for your car with added supplies like fire extinguishers, maps, and extra clothing to protect against potential hazards on the road.
Keeping Your 'Go Bag' Up-to-Date
A 'Go Bag' is only effective if its contents are usable and relevant. Here’s how to maintain it:
Seasonal Updates: Add weather-appropriate gear, like sunscreen in summer or thermal blankets in winter.
Check Expiration Dates: Replace food, water, and medications regularly.
Test Equipment: Periodically test items like flashlights to ensure they're operational.
Refresh Personal Documents: Update copies if IDs or insurance details change.
Creating and Practicing a Family Emergency Plan
Even the best 'Go Bag' won’t help if your family is unsure what to do during an evacuation. Take time to build and practice a solid emergency plan:
Establish Family Roles
Assign specific tasks to each family member, so everyone knows their responsibilities during an evacuation.
Plan Evacuation Routes
Identify at least two evacuation routes that lead to safety, as one may be blocked during an emergency.
Designate a Meeting Point
Choose a safe, predetermined location where your family will regroup after evacuating.
Practice Evacuation Drills
Conduct mock evacuation drills to ensure everyone moves quickly and calmly when needed.
Additional Steps to Protect Your Home Before Wildfire Season
Preparedness doesn’t stop at having a 'Go Bag.' Home maintenance can help increase safety during wildfires.
Create Defensible Space
Remove flammable debris 30-100 feet from your home to slow fire advancement.
Reinforce Fire-Resistant Materials
Consider replacing roofing, siding, and vents with fire-resistant materials.
Stay Updated
Sign up for local fire alerts and weather notifications to stay ahead of potential threats.
Preparedness Saves Lives
When wildfires threaten, preparation equals peace of mind. With a well-packed 'Go Bag,' a practiced family evacuation plan, and proactive home safety measures, you can respond to emergencies swiftly and confidently.
Take the time to prepare today to protect what matters most—your family and home. Share this guide with friends and family, so they too can stay safe and ready for wildfire season.
