10 Common Briggs & Stratton Intek V-Twin Problems
1. The engine won’t start
So, you’ve turned the key, and your Briggs & Stratton Intek V-Twin engine won’t start?
Usually, the issue boils down to a few key areas. The spark plug wire might be disconnected, dirty, or fouled.
A weak or dead battery can also be the culprit. Then, a clogged fuel line or a faulty ignition coil is possible. Any of these can stop your engine from firing up.
- Check Spark Plugs: Inspect spark plugs for dirt or damage. Ensure they’re well connected. If they look worn or fouled, replace them.
- Battery Test: If the battery is weak, charge it. If old, replace it. A healthy battery provides the necessary power for the engine to start.
- Inspect Fuel Line: Check for clogs in the fuel line. Replace the fuel filter if it’s dirty to ensure a consistent fuel supply.
- Check Ignition Coil: Use a tester to assess the ignition coil’s functionality. If it’s faulty, replace it to maintain a strong spark for ignition.
2. Engine runs rough
If your Briggs & Stratton Intek V-Twin engine runs rough, it’s not performing at its best. This can be due to a few reasons.
Often, a dirty or clogged air filter is to blame, restricting airflow and causing the engine to run unevenly.
Another culprit might be stale or contaminated fuel in the tank. A worn-out spark plug can also lead to rough running as it struggles to ignite the air-fuel mixture.
Solutions – Troubleshooting Steps:
- Clean or Replace Air Filter: Remove and clean the air filter; if it’s heavily soiled or damaged, replace it to ensure proper airflow.
- Fresh Fuel: Drain old or contaminated fuel, fill the tank with fresh gasoline, and add a fuel stabilizer to prevent future issues.
- Check Spark Plug: Examine the spark plug for wear, fouling, or damage. Replace it if necessary to ensure a strong spark.
When your Briggs & Stratton Intek V-Twin engine starts overheating, it’s a sign that something’s amiss.
Overheating can happen for several reasons. One common cause is blocked cooling fins or radiator, preventing proper heat dissipation. Low coolant levels can also lead to overheating.
Watch for rising temperature gauges or steam from the engine area to identify the issue.
- Clear Cooling Fins: Check the cooling fins for debris and dirt buildup. Clean them well to ensure efficient cooling.
- Top-Up Coolant: Ensure your engine has enough coolant. Fill it to the recommended level with the appropriate coolant mixture.
4. Oil leak
Noticing an oil leak in your Briggs & Stratton Intek V-Twin engine can be worrying. The usual suspects are worn gaskets and seals, loose or bad oil filters, and harm to the oil pan.
A cracked engine block or too much oil pressure can also create leaks in severe cases.
- Replace Worn Gaskets and Seals: Look closely at your engine’s gaskets and seals. Swap out any that look old or damaged.
- Check and Tighten the Oil Filter: Ensure it’s good and snug when using the oil filter. If it needs to be looking right, get a new one.
- Repair or Change the Oil Pan: If the oil pan is beaten up, it might need fixing or swapping for a new one to stop the leak.
- Fix Cracked Engine Blocks: Cracks in the engine block are a big deal. You’ll likely need a professional mechanic to check and repair them.
- Manage Oil Pressure: If high oil pressure is the issue, you might need an oil pressure regulator to prevent gasket issues and stop oil from escaping.
5. Excessive vibration
Feeling your Briggs & Stratton Intek V-Twin engine shake too much? It could be due to unbalanced engine parts, like a bent cooling fan blade or crankshaft.
Loose motor mounts or a damaged flywheel key can also cause excessive vibrations. Addressing these issues ensures smoother engine operation.
- Check and Fix Engine Parts: Look closely at the engine parts we talked about earlier. If anything looks bent or broken, it might need repairing or replacing.
- Tighten or Replace Motor Mounts: If the engine seems loose, check those big screws holding it in place. Tighten them up, or get new ones if they’re not working right.
- Examine the Flywheel Key: If vibrations don’t stop, look at that key inside the engine. If it’s damaged, put in a new one to make everything spin smoothly again.
If your Briggs & Stratton Intek V-Twin engine keeps stalling, it’s frustrating. Several things can cause this.
A dirty carburetor is often the culprit, or it might be a bad spark plug gap. Sometimes, old fuel can clog things up, or a faulty ignition coil can cause stalling.
- Clean the Carburetor: Remove and thoroughly clean it if it’s dirty. A clean carburetor ensures the engine gets the right air and fuel for smooth operation.
- Replace Spark Plugs: Swap out old or fouled spark plugs for new ones to ensure a strong spark for ignition.
- Fresh Fuel: Drain any old or stale fuel from the tank and replace it with fresh gasoline. Good fuel keeps the stratton engines running smoothly.
- Check the Ignition Coil: Ensure the ignition coil is in good working order. If not, replace it to ensure proper spark and consistent engine performance.
7. Excessive smoke
Seeing too much smoke from your Briggs & Stratton Intek V-Twin engine can be worrying. The color of the smoke can tell you what might be wrong with your engine. Let’s break it down.
Different Smoke Colors and What They Mean:
- Blue Smoke: Blue smoke means your engine is burning oil with fuel. It can happen because of issues like worn piston rings, damaged cylinder walls, or a faulty crankcase breather.
- Black Smoke: Black smoke means your engine is using too much fuel. Causes are a dirty air filter, problems with the carburetor, or issues with ignition timing.
- White Smoke: White smoke means coolant or water is getting into your engine’s combustion chamber. It’s due to a damaged head gasket, a cracked cylinder head, or a warped engine block.
- For Blue Smoke: To reduce blue smoke, fix worn piston rings, damaged cylinder walls, or a faulty crankcase breather.Replacing these parts or fixing the breather.
- For Black Smoke: Check and fix issues with the air and fuel mixture, like a dirty air filter, carburetor problems, or wrong ignition timing. Clean or replace the air filter, adjust the carburetor, or check and fix ignition timing.
- For White Smoke: Find and fix problems that let coolant or water into the combustion chamber. It might need professional repair or new parts like the head gasket, cylinder head, or engine block.
When your Briggs & Stratton Intek V-Twin engine starts surging, it’s not running smoothly.
Surging occurs due to irregularities in the engine’s operation. A clogged carburetor can cause it, a blocked fuel supply, or air leaks in the intake system.
- Clean the Carburetor: A dirty carburetor messes up how fuel mixes, making the engine surge. Cleaning it makes sure the fuel and air mix well for smoother running.
- Check the Fuel Supply: Stuff blocking the fuel supply can make fuel delivery uneven, causing surging. Make sure fuel flows without any obstacles.
- Inspect for Air Leaks: If air leaks into the intake system, it messes up how fuel and air mix, leading to surging. Look for leaks and seal them to keep the engine running right.
9. Burning oil
When your Briggs & Stratton Intek V-Twin engine starts burning oil, it’s a sign that something isn’t quite right inside.
Burning oil may occur because of worn piston rings, damaged or old valve seals, or problems with the crankcase ventilation system. These issues allow oil to enter the combustion chamber and burn along with fuel.
- Replace Worn Piston Rings: Worn piston rings need replacement to prevent oil from entering the combustion chamber.
- Address Valve Seal Leaks: Fix or replace damaged or old valve seals to prevent oil from entering the combustion chamber.
- Fix Crankcase Ventilation: Ensure the crankcase ventilation system works properly to reduce oil consumption and burning.
10. Briggs and Stratton v-twin carburetor problems
The carburetor in your Briggs & Stratton Intek V-Twin engine plays a crucial role in mixing air and fuel for combustion.
When it has problems, your engine’s performance can suffer. Let’s explore some common carburetor issues and solutions:
Common Carburetor Problems:
- Clogged Jets: Over time, the tiny openings (jets) in the carburetor can get clogged with dirt or deposits, disrupting fuel flow.
- Sticky Float: A sticky float can cause irregular fuel levels in the carburetor, affecting the air-fuel mixture.
- Dirty or Stale Fuel: Using old or contaminated fuel can lead to carburetor issues, as it can leave behind residue and clogged passages.
- Clean or Replace Clogged Jets: Inspect and clean the jets to ensure proper fuel flow. In severe cases, replacement may be necessary.
- Address Sticky Float: Clean the float and its chamber, ensuring it moves freely. Lubricate or replace if needed.
- Use Fresh Fuel: Always use clean, fresh fuel to prevent carburetor problems caused by stale or contaminated fuel.
