Q: What is the oil capacity of the FA210 engine?

The FA210 engine has a maximum oil capacity of 0.60 liters (0.64 quarts) . The manual recommends a good quality motor oil of category SC with a viscosity suitable for the operating temperature: Below 10°C: SAE10W30 Normal temperature: SAE30 From 35°C: SAE40 For optimal maintenance: Check the oil level before each use by placing the engine on a flat surface Change the oil every 50 hours of operation (first change) An insufficient oil level can cause serious damage to the engine (seizing).

Q: The high voltage wire is not making good contact with the spark plug, how to fix it?

Poor contact between the high voltage wire and the NGK BM-6A spark plug is a common cause of engine malfunction. Here’s how to check and fix it: Checking and Cleaning Disconnect the cap from the high voltage wire of the spark plug. Inspect the inside of the cap : look for signs of corrosion, soot, or moisture that may prevent contact. Clean the inside of the cap with a dry cloth or cotton swab. Also clean the top of the spark plug (the upper electrode) where the cap connects. Reassembly and Testing Firmly push the cap onto the spark plug until you feel slight resistance. It should be well seated. Visually check the spark : place the spark plug against the metal engine block and pull the starter several times. You should see a clear blue spark between the electrodes of the spark plug (recommended gap: 0.6 to 0.7 mm ). If the spark is weak or absent, check that the contact is properly established at the cap. If after cleaning the contact remains poor, the cap or wire may be worn and need replacement.

Question 1

What is the oil capacity of the FA210 engine?

Accepted Answer

The FA210 engine has a maximum oil capacity of 0.60 liters (0.64 quarts).

The manual recommends a good quality motor oil of category SC with a viscosity suitable for the operating temperature:

Below 10°C: SAE10W30
Normal temperature: SAE30
From 35°C: SAE40

For optimal maintenance:

Check the oil level before each use by placing the engine on a flat surface
Change the oil every 50 hours of operation (first change)
An insufficient oil level can cause serious damage to the engine (seizing).

Question 2

How to adjust the ignition coil when it is above the flywheel?

Accepted Answer

If your ignition coil is positioned above the flywheel of the FA210 engine, it is crucial to adjust the gap between its core and the flywheel magnet for optimal spark.

Adjustment Procedure

Loosen the mounting screws slightly of the coil without completely removing them.
Gently bring the coil closer by lowering its core towards the magnet that passes underneath during rotation.
Set the precise gap: maintain a clearance of 0.3 to 0.5 mm between the core and the magnet (equivalent to the thickness of a thin sheet of paper).
Tighten the screws gradually to secure the coil in this position.
Manually test: turn the flywheel by hand for a full rotation to ensure that no part is rubbing or touching.

Expected Result: an adjustment that is too far away results in a weak or orange spark instead of blue, and starting difficulties. By bringing the coil closer correctly, you should achieve a brighter spark and smoother engine operation.

Question 3

When I remove the starter, the engine stutters. I discovered a missing spring from the starter system that I reinstalled.

Accepted Answer

Excellent discovery! The spring you found is a key component of the starter/choke system of the FA210 engine.

Role of the spring:

It ensures the proper functioning of the choke mechanism
When it is missing, the choke does not close properly during cold starting
This causes an unbalanced air-fuel mixture when you transition from starting to normal operation, which leads to the stutters (“vroom vroom”) you observed

Now that you have reinstalled it:

Set the choke lever to the closed position for starting
Once the engine is warm, switch it to the half-open position according to the FA210 procedure
Test the transition: the engine should now run smoothly without stutters
Check that the spring is securely attached and that it did not tighten during reinstallation

If the problem persists, check that the spring is correctly positioned and that no other component of the choke mechanism has been damaged.

Question 4

Why does the engine start but run unevenly with jerks?

Accepted Answer

An engine that starts but runs unevenly with repeated jerks can have several causes on the FA210. Here’s how to diagnose and resolve the issue:

Priority Checks

Clean the air filter - according to the FA210 manual, the filter should be cleaned every 25 hours of use. A clogged filter limits air intake and causes jerks. This is the most common cause.
Check the engine oil - insufficient or too old oil causes jerks. Oil change is recommended every 50 hours. Check the level before each use as indicated in the manual.
Check the ignition coil position - it should be at the correct distance from the flywheel to generate a normal spark. If it is too far away, the spark weakens and the engine misfires. Check the gap with a feeler gauge.
Inspect the spark plug - a dirty, worn, or loose spark plug causes misfires. Clean it or replace it if it is too worn. Ensure that the ignition wires are properly connected.
Check the fuel - use fresh, high-quality gasoline. Gasoline that is too old (stored for several months) oxidizes and does not ignite properly.

Tip: Start with the air filter and engine oil, as these are the most common causes of this type of problem on the FA210. If the problem persists after these checks, check the ignition coil as described in step 3 of your manual.

Question 5

Accepted Answer

Poor contact between the high voltage wire and the NGK BM-6A spark plug is a common cause of engine malfunction. Here’s how to check and fix it:

Checking and Cleaning

Disconnect the cap from the high voltage wire of the spark plug.
Inspect the inside of the cap: look for signs of corrosion, soot, or moisture that may prevent contact.
Clean the inside of the cap with a dry cloth or cotton swab.
Also clean the top of the spark plug (the upper electrode) where the cap connects.

Reassembly and Testing

Firmly push the cap onto the spark plug until you feel slight resistance. It should be well seated.
Visually check the spark: place the spark plug against the metal engine block and pull the starter several times. You should see a clear blue spark between the electrodes of the spark plug (recommended gap: 0.6 to 0.7 mm).
If the spark is weak or absent, check that the contact is properly established at the cap.

If after cleaning the contact remains poor, the cap or wire may be worn and need replacement.
