It is the most thwarting and distressing situation since you may lose control of the vehicle and get into a fatal accident.
But hold on! We are here to guide you through all the causes of these complications.
Your ATV might die after letting off the throttle due to carburetor or fuel issues, incorrect idle speed, or a dirty air filter.
In this article, we are going to discuss why your ATV dies after letting off the throttle and how to fix this issue.
Reasons Why Atvs Die And How To Fix It
1. Clogged Air Filter
Sometimes air filters in the vehicle trap dirt and dust from the surroundings and when the throttle is released this dirt doesn’t let airflow towards the engine and it stalls.
- First of all, locate the air filter that usually lies beside the engine.
- Remove the filter and clear all the debris with the help of a soft brush.
- Reinstall the filter after cleaning it and make sure it is securely fastened.
- Run the engine to check if everything is working smoothly.
2. Mechanical Problems
Sometimes ATVs undergo some mechanical issues and it is mandatory to fix them as soon as possible otherwise it gets ATV stalled.
- Firstly, try to find out the real issue. Check all the inner components.
- You can take help from the user manual if things are unclear.
- Now inspect all the parts of your vehicle. If they need any repair then go for it otherwise replace much damaged parts.
- One issue is resolved to fasten everything properly in the right place.
- Test the ATV by taking it for a ride and check everything is running perfectly.
3. Malfunctioning Fuel Filter
If there is any problem with the fuel filter then you can expect it to stall the engine. When the fuel filter doesn’t work efficiently then it halts the delivery of fuel to the engine which causes engine issues.
- The first thing you need to do is to locate the fuel filter that is usually found near the fuel tank.
- Then remove this fuel filter and check all signs of damage.
- Repair the filter if there are only minor cracks or you will need to reinstall a new one.
- Install a filter cautiously with the help of manuals.
- Once you are done with all these things then run the engine and see if everything is working flawlessly.
Malfunctioning carburetor side effects
If the carburetor is not working well then it disturbs the mixture of air and fuel which further causes the engine to stall. It might be the reason the engine stops working when the throttle is released.
- Carburetor is always found attached to the engine. Unscrew its bolts with the help of a wrench.
- Take a soft brush and clean all parts carefully.
- Check if there are any cracks or leakage. Replace that part that cannot be repaired.
- Reinstall the carburetor to its place and test drive your ATV to ensure it is working well.
5. Low Idle Speed
Sometimes when we let the throttle off the engine remains unable to maintain the required speed which becomes the reason to stall the engine and ATV dies.
- Firstly, warm up the engine to set the idle speed.
- Locate the idle adjustment screw that is usually found on the carburetor.
- Take a screwdriver and turn the screw clockwise to adjust the required speed.
- Use a tachometer to check the idle speed.
- Now run the engine to check everything is working perfectly.
In short, an ATV dies after letting the throttle off due to a malfunctioning carburetor, dirty air filter, fuel, or mechanical issues. Here we have discussed all the potential causes along with their solutions. If the problem persists then take your vehicle to a professional to have it fixed properly.
