A lack of acceleration in these units is most likely a fuel delivery related issue. It may possibly be time for a diaghram kit or carb rebuild kit to be installed in your carburetor. Ethanol in the gas deteriorates the parts that accomplish the acceleration procedure and may need to be replaced as they don't function anymore.
Many other things can affect these little machines as well such as clogged air filters, clogged crank case vent, clogged mufflers/exhaust ports./ spark arrestor screens...but more often than not, your problem is a carburetor issue.

So you don't have echo


No Spark can be one of 3 faults.
The wire to the spark plug is either shorted somewhere along its length. An open circuit along the wire coming out of the magneto or
the magneto is not generating a spark.
Best way to test for a spark is to use a neon test lamp.
Hold one end and bring the other end close to high voltage wire under test. Test on your running car first.
Trace the HV wire back to the magneto on side of engine. rotate engine by hand to get magneto to generate a current. Remove spark plug to allow engine to rotate easier without compression.
The high voltage is generated from a coil inside magneto assembly.
Good Luck

No spark. I pulled off the kill wire to eliminate that cause and still no spark. No visible damage. I pulled off the top metal on the engine to look at the magneto. It appears okay. But no spark.


Hi Dale, if you have isolated the kill wire at the magneto then the magneto is faulty and will have to be replaced. Regards Phil.

The magneto is self contained and the primary winding is grounded via the throttle stop, flywheel brake, or the low oil level sensor to ground the magneto enough to stop the spark from jumping the spark plug gap.
First check the oil level and make sure it is fully serviced.
Second check the Flywheel brake switch to see of the cable needs re-adjusted or replaced. There is a lever on the brake actuator that makes a ground on the primary of the magneto. ANY gound on the wire that goes from the flywheel brake, the throttle control (if so equipped) or the low oil level sensor will stop the engine from having spark. There is no condensor. The magneto is excited by the magnet in the armature each rotation of the fly wheel. Grounding of the magneto primary rreduces / stops the function of the magneto high voltage output.

You need to find out what is grounding the magneto primary when the engine should be in a running state.

Thanks for choosing FixYa,

Id like to know if you can test your magneto without a multi circuit tester ? if i am getting spark, is my magneto still good? how do i read the numbers to know what year i in fact have ?


If you are getting a strong, blue, spark on a known, good spark plug, then the magneto is good. If the spark is weak (barely visible), then it is most likely the clearance or rust build up.

The easiest thing to do is check for rust on the surface of the magneto and the surface of the pick-up coil. Emery cloth is good for removing rust on both. Then check for the clearance between the pick-up coil and the magneto. The closer to the magneto, the more powerful the spark (but rotate the magneto to ensure it never touches). When you loosen the screws on the pickup coil to adjust, make sure you have a business card to place between the surfaces to keep them from touching. The strong magnet in the magneto will pull the pickup coil to itself. Tighten the screws and remove the business card. Check for clearance as you rotate the magneto.

The only thing that can go bad in a magneto situation is the pickup coil. So, if you're getting a spark, it most likely is not the pickup coil because it will either produce a spark or won't.

What would cause no spark? the mower is a masport 8/02 two stroke. Will not start and I have changed spark plug and cleaned every thing but still nothing.


Your spark plug wire may be damaged, or your magneto may be too weak to generate a spark. You also have a kill switch wired to your magneto, and a condensor. I would start by cleaning the contacts of the magneto and then check the gap between the magneto and the flywheel. The gap between the flywheel and magneto should be .010". I would start by checking the kill switch wire for damage. If any damage is suspected, replace the kill switch. Next, I would have the magneto tested or replaced. Also, check all your ground wires for damage, or loose contacts.

When you are checking for a spark, you should have the spark plug installed in the spark plug wire as normal, but not installed in the engine. The spark plug base should be grounded to the engine while trying to start and checking for a spark. If there is a weak spark, this is probably due to a worn magneto.

It all depends on the model of engine. If it is a twin engine doesn't it have two magnetos.Very unusual for both to go bad It will depend on the type of ignition(points or solid state) The wire going to the magneto could be the kill switch (kills when grounded) Disconnect it and see if you get spark. IF so then it is in your safety/ignition circuit. If you replace magneto usually the gap is .008-.012

No fire to the plug


that could be from a short in the circutry even as simple as some debri build up around the blade brake magneto ground contact point that is grounding the magneto so spark can not continue to the plug could also be a fouled spark plug or could also be the magneto condenser attached to the magneto has burnt thus looseing capability to disperse the electrical energy to the spark plug, and worse case senario is the magneto is internally damaged from use also possably the magneto's air gap to the magnets on the flywheel is to exssesive for energy production hope this helps Steve

It wont spark at all. No fire. Just put a new spark plug so that's not the issue. This lawnmower is only 1.5 years old. Thanks


Could be magneto bad, wire from magneto bad, ground on magneto bad, or the clearance between the flywheel and the magneto is rusted up if it was outside. Clean flywheel with sandpaper and set magneto gap using a match book flap.

Alright, remember that 2-Stroke motors are meant to do 2 things:
Break down, then Frustrate you.

So, here we go: (Electrical)

Rotor Magnets, Magneto (ignition coil), Spark Plug Wire, Spark Plug, Spark Plug Ground (Cylinder Head).

In that order!

Check your "fire" from the Magneto:

1. Check your Kill Switch. In other words, leave everything normal, and unhook it. Did she start? Kill Switch it is! Kill Switch/Wire comes from the Magneto (single wire/ground) to the Switch itself. So check that wire AT the Magneto (Is it loose and grounding out? Is the Kill Switch grounding you out where it is, because of crud, junk, or because it is touching the block when it is not supposed to?)

2. Check your Spark Plug Wire. Easy, unook it from the plug, stick your finger in, give it a crank (non-MultiMeter way). Did you get shocked? Then it ain't your Plug Wire and Magneto!

With a Multi-/Volt Meter, simply hook her up, and check for juice WHEN you pull the rope. If you got juice, it ain't your Plug Wire or Magneto!

Checking Spark the "normal" way: Grab the Plug with a pair of insulated pliers, hold the plug end against the cylinder head, and pull your rope. Any Spark? What color?

3. STILL no fire. It leaves: Magneto and Plug Wire.
Luckily, they are both in the same place! Tear your blower down, and check to see if the Magneto has slipped out of place (gap is WAY out), or if the Plug Wire has worn to the point it is grounding you out. While you are there, check your Kill Switch wire, to see if she is grounding you out then and there.

4. STILL no fire. That means: Magneto Failing, or Magneto JUNK.
Buy another one, replace it! (Or steal one from another junk Blower/Weedeater. These things are fairly standard, and easy!)
Or, Bad Plug Wire. Meaning she has failed out on you.
Wait......that means: Replace your Magneto! Lucky the things are built together right?
