The causes and solutions for your Briggs & Stratton intek v- twin’s are discussed here.

1. Engine Won’t Start


If the Briggs & Stratton Intek V-Twin Engine won’t start, there could be several causes.

Common causes include a lack of fuel, spark, or air, a faulty spark plug, or a clogged carburetor. It is also possible that the engine is flooded with too much fuel, or that the battery is dead or low on power. 

If the engine has been sitting for a long time, it is also possible that the carburetor needs to be cleaned or rebuilt.

The Fix

  • Inspect the spark plug. Make sure it’s connected and in good shape. If needed, replace.
  • Check gasoline supply. Check sure the fuel tank is full and the fuel line is clear.
  • Inspect air filter. Make sure it’s clean and debris-free. Clean or replace as needed.
  • Engine oil level should be checked. Make sure it’s clean and at the right level.
  • Carburetor inspection. Ensure that the jets are clear and debris-free. Clean or replace as needed.
  • Inspect the ignition system. Check that the ignition coil is working and the spark plug wires are connected.
  • Check the battery. Make sure it’s completely charged and securely connected.
  • Inspect the recoil starter. Ensure that the recoil starter cord is not damaged or jammed. If needed, replace.

2. Engine Runs Rough 

The most common causes are dirt and debris in the air filter, a clogged fuel filter, loose or damaged spark plug wires, and spark plugs.

Additionally, the carburetor may not be adjusted properly or need a replacement for using it over time.

The Fix

  • Check the air filter for dirt or debris. A clogged filter can cause the engine to run rough. 
  • Check the spark plugs for signs of wear or fouling. If they are old or worn, replace them. 
  • Check the fuel filter. If it is clogged, replace it.  Check the fuel lines for any cracks or leaks. If there are any, replace them. 
  • Check the carburetor for any obstructions or dirt. Clean or replace the carburetor as needed. 
  • Check the valve clearances and adjust them as needed.
  • Check the ignition timing and adjust it as needed.

3. Overheating

The most likely cause of an overheating Briggs & Stratton Intek V-Twin engine is a lack of proper maintenance.

This can include a clogged air filter, a malfunctioning cooling fan, or a dirty engine oil. If the engine is not serviced regularly, it can cause the engine to overheat due to a lack of proper cooling.

The Fix

If your Briggs & Stratton Intek V-Twin Engine is running hot:

  • Check is the oil level. If the oil level is low, then you should add oil and check if the engine runs more smoothly.
  • If the oil level is fine, then you should check the air filter to make sure it is clean and not clogged. If the air filter is dirty or clogged, then it should be replaced.
  • You should also check the spark plugs to make sure they are clean and not fouled. If they are fouled, then they should be replaced.
  • Finally, you should make sure the cooling fan is working properly and that there are no obstructions in the air flow.

4. Oil leak

The most common cause of your Briggs & Stratton Intek v-twin engine oil leak for low oil level. Oil leaks can occur due worn or damaged gaskets, worn or damaged seals, a damaged crankshaft, or a damaged oil filter.

The Fix

If your engine is running and leaking oil:

  • Check the oil level first. Low oil levels may cause leaks.
  • If the oil level is right, a fractured oil seal, gasket, or other component may be leaking oil. Before adding oil, inspect the engine and find the leak.
  • If the leak is serious, take the engine to a qualified service center.

5. Excessive Vibration

The most common cause of excessive vibration in a Briggs & Stratton Intek V-Twin engine is an unbalanced flywheel. The flywheel can become unbalanced over time due to wear or damage.

Other possible causes of excessive vibration include loose mounting bolts, worn or damaged components in the engine, a faulty spark plug, or a damaged engine crankshaft.

The Fix

To fix this issue:

  • Replace the crankshaft and pistons if the engine is out of balance.
  • Check the flywheel, balancer, and connecting rods for damage. Replace worn or broken parts.
  • Furthermore check the spark plugs, air filter, and fuel filter for excessive wear. Replace any worn parts.
  • Finally, repair worn engine mounts.

6. Stalling

Stalling can occur in Briggs & Stratton Intek V-Twin engines due to a variety of reasons. It could be due to a clogged fuel filter, a faulty spark plug, a faulty carburetor, a weak battery, a faulty ignition coil, or a clogged exhaust.

Additionally, it could also be caused by low oil levels, a dirty air filter, a weak fuel pump, or a broken flywheel key.

The Fix

To solve the problem with stalling:

  • First check the air filter, spark plug, and spark plug wire for debris to fix stalling.
  • If these parts are clean, verify the fuel-to-air ratio. Fix the fuel-to-air ratio.
  • If the problem persists, a certified technician should service the engine owing to a faulty spark plug wire or other technical issues.

7. Excessive Smoke

An inadequate fuel-to-oil ratio, spark plug gap, air filter, fuel line, pump, or carburetor can cause a Briggs & Stratton Intek V-Twin engine to smoke excessively.

The Fix

  • First, check the fuel-to-oil ratio. Adjust as necessary.
  • Check the spark plug gap next. If not, tweak it.
  • Clean the air filter next. Replace if dirty.
  • Check the fuel line for leaks. Replace it if necessary.
  • Afterwards, test the gasoline pump. If it is not in proper condition, replace it.
  • Clean the carburetor last or replace it.
