In the realm of petrol garden machinery, a hunting engine pertains to a situation where the engine's RPM (revolutions per minute) experiences fluctuations or "hunting," resulting in uneven performance and a wavering sound. This occurrence is commonly observed when the engine shifts between running too swiftly and too sluggishly, akin to it searching for a steady operational speed. Engine hunting can manifest in various petrol-powered equipment like lawnmowers, chainsaws, trimmers, and other garden implements.
Potential Triggers of Engine Hunting:
1. **Air-Fuel Mix Irregularities**: Improperly calibrated carburetor settings, obstructed fuel jets, or a soiled air filter can disrupt the balance of the air-fuel mixture, culminating in engine hunting.
2. **Carburetor Concerns**: A malfunctioning or grimy carburetor can impede accurate fuel delivery, causing instability in engine performance.
3. **Fuel Complications**: Stale or contaminated fuel can hinder combustion and engine operation, giving rise to the hunting phenomenon.
4. **Spark Plug Issues**: A fouled or impaired spark plug might lead to inconsistent ignition, thereby triggering engine hunting.
5. **Vacuum Leakages**: Any leaks in the engine's intake system can create air imbalances, leading to the hunting behavior.
6. **Throttle Linkage Challenges**: Problems with the throttle linkage or governor mechanism can result in sudden speed shifts and engine hunting.
7. **Exhaust Blockages**: A clogged or partially obstructed exhaust system can hamper exhaust flow and contribute to hunting.
Possible Remedies for Engine Hunting:
1. **Clean or Replace Air Filter**: Ensure the air filter is clean and devoid of debris. Replace it as needed.
2. **Inspect and Adjust Carburetor**: Validate that the carburetor is precisely adjusted as per the manufacturer's specifications. Clean the carburetor and fuel jets if required.
3. **Use Fresh Fuel**: Always opt for fresh, high-quality fuel with the correct fuel-to-oil ratio.
4. **Evaluate and Replace Spark Plug**: Scrutinize the spark plug for fouling or damage. Replace it if necessary and ensure the gap is accurate.
5. **Address Vacuum Leaks**: Thoroughly examine the intake system for any leaks or loose connections. Seal any vacuum leaks.
6. **Clean Fuel System**: Regularly cleanse the fuel lines, fuel filter, and fuel tank to thwart debris accumulation.
7. **Governor Adjustment**: Inspect the throttle linkage and governor mechanism for proper functioning, making adjustments as required.
8. **Inspect Exhaust System**: Conduct a thorough check of the exhaust system for any blockages or hindrances. Remove any obstructions found.
9. **Professional Servicing**: If the issue persists, consider enlisting the assistance of a professional mechanic or authorized service center for a comprehensive inspection and rectification.
Kindly note that working on petrol engines demands a certain level of mechanical know-how and safety precautions. Should you lack confidence in diagnosing or rectifying the issue independently, it is advisable to seek the expertise of a qualified technician to ensure meticulous and secure repairs.

Thanks fixed my problem in five minutes!
We are really glad you are getting on well with your new lawnmower! We're sure the strimmer will more than meet your expectations!
Superbly explained video again. Thank you!
Not a problem! Glad it could help.
Thank you, Adrian. Very well explained. We have a similar engine with these symptoms at light loads. Under heavy load (it is a generator) it is okay. I'm going to try this first. Cheers.
Usefull video, thank you
No problem Christos!
Thanks Adrian, it fixed my lawnmower hunting problem - seemed like there was no hole there at all, to be honest!! The only thng now is it intermittently backfires, any suggestions? Thanks again.
That's great thank you, my problem is the same carb on a water blaster, but it has always done this, putting me out a bit in terms of finding the problem. God I love the internet for finding a solution to a problem, no excuse these days for being ignorant. Back to the garage now.
Best of luck to you!
Is there a adjustment for the throttle? My mower is only running at one speed not high rev but medium only.
Fantastic tutorial thank you very much my mower is now running like new.
Really great to hear that this helped you!
