Hello pbck98:

>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block. >>Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**
>>If you have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
For Better Assistance;
>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
Please, Do Not Hesitate, If I Missed Something or you Hit a Snag or this Does Not Correct the Problem, I am Here if You Require More Assistance.
Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Be Happy. Thanks.

Good Luck

SOURCE: yard machine 21'' push mower runs 2 to 3 seconds cuts off.

Tip the mower up on it's side with the dipstick tube on the down side and collect it in a suitable container. The gas you can do the same. When I drain old fuel, I mix it with a lot of fresh fuel and a bottle of dry gas then run it in my car.

SOURCE: Little spark

check the gap on your plug. .030 is what it should be. also make sure that your
kill cable is working properly and not grounding the engine out.
the gap for you magneto should be set to .010 to .012
loosen up the magneto insert a standard business card or 3x5 card
then turn the flywheel so that the magnet on the flywheel pulls the magneto into it. then tight the magneto mounting screws down. try spark now. always use fresh gas. -no-water- if in doubt throw it out.
gas is BAD after only 30 days.

You can make sure your carburater is clean. Clean the filter. Some time you can get a enpty coffee can and pour some gas in it and rinse the filter out repeatedly. Check the oil also that should get you back on the green..............: )

SOURCE: Yard-man model 12a-979L401 won't start (9 years old)

Hi,
My dad always taught me, rest his soul, that basic 101, if you have gas getting to spark, SOMETHING out to happen.
I'll ask a series of questions and propose some possible solutions. Hopefully we'll crack this mystery. Warning, this might be a tad lengthy... ha
1. Is the spark plug firing?
To check the coil that sends spark to your spark plug and the plug itself:
You can remove the spark plug from your engine and reconnect it to the spark plug wire while it just lays on your mower. pull the starter rope (make sure you're holding down the kill lever on the handle). Look at your plug end as you pull the rope.
Got spark? If yes, go to the next step, flagged ***. If no, look at the end of your spark plug that would go into the engine. The "L" shaped finger should be gapped from the small circular shape on the plug... this is the "gap". Your manual may provide specs on how wide this gap should be. If there is no gap, your plug won't work properly. The "L" shape is a soft metal and can be bent... create the proper gap. Try the test again to see if the plug is sparking. If not, you may have an issue with your coil.
***Yes to spark. Let's look at the gas issue now. OPTION 1. I will tell you that in my experience, water in gas is a major culprit for a mower not running. You've replaced all the filters... good.
I'm not sure of your mower, but most models have a "bowl" bolted to the bottom of the carburator. Sometimes moisture can get in the gas, get trapped in the bowl and won't go away or won't allow gas to get to the spark. Loosen the bolt... it's ok if gas from the bowl spills from this, the bowl doesn't hold much gas and it won't drain your tank. Plus, this means your carbuator is allowing the gas from the tank to the bowl. As you are looking at the gas spilled on the mower deck, see if there are beads of water in it. As you know, water and gas doesn't mix. This would be a tell tale of the problem. I would carefully remove the bowl from the carb and wipe it dry, then reassemble the bowl.
To be on the for sure side that you have no more water in your system, you could disconnect your fuel line from the gas tank and drain it out. Use a jar or container... you can see water in the bottom of it. You can reuse the gas too... just don't include the water!
OPTION 2. If your carb and tank are now H2O free and you're still getting to results, you may have a clogged jet on your carburator. This little pin-hole passage allows gas to pass through to the spark. Sometimes a mower sitting up a while, can cause a laquer effect to gas and it can block this passage. Removal of the carburator from the engine is required and a simple pin can be pushed through this passage to knock a "plug" out.
Geez I hope I didn't miss anything! ha
Good luck to you... I hope it's a quick and easy fix.

No spark after renew of coil and plug.


Assuming you have read other posts here about air gap and have it set approximately correct, the next thing to do is disconnect the cutout wire from the coil (small wire with spade connector). When you hit the kill switch, this wire is grounded to the chassis of the saw, which prevents the ignition coil from generating a spark. Often, the insulation on this wire can fail, allowing the wires to short against a metal part, or the kill switch may be faulty.
If you have spark with this wire disconnected, check the wire itself for any breaks. If it looks good, then the only thing left to check is the switch.
****Don't try to start and run the saw with the wire disconnected, because if it starts, you'll have no way to stop it****

Engine won't fire-no spark. New plug.


Check stop switch mechanism (kill switch, safety interlock cable). Check for damaged coil wire to spark plug. Make sure coil wire is completely seated onto spark splug. Sometimes the coil wire gets damged and shorts out to the shroud.

22 hp 2plugs 1 side not firing


Sounds like you may have a bad spark plug or coil..first remove the plug wire from the one not firing..using a rubber handled pliers hold the plug wire close to the plug tip or any metal part of the motor..and crank engine if you see a spark it most likely is the plug..pull the plug out and place the wire back on and do the same thing holding the plug close to the metal, if no spark change the plug..if none coil is bad..just follow the plug wire back to its beginning..the coil. It is attached by two bolts or screws,,check and see if they are tight and there is space between the coil and the flywheel..if it is loose or no space reset the clearance by using a business card as a gauge between the coil and flywheel and retighten and check for spark..If everything iis tight and clearance is ok..remove the coil and replace with a new..use the business card as a gauge...good luck.

Spark plugs


Check this SPARK PLUG REPLACEMENT - REMOVAL PROCEDURE

1_23_2012_5_10_32_pm.jpg

1. Remove the ignition coils (lines at end this document), then return here once you have gotten the Coil
Packs off and precede with step 2 from here.
2. Clean the spark plug recesses with low pressure air. CAUTION: Wear safety glasses
when using compressed air, as flying dirt particles may cause eye injury. NOTE:
Clean the spark plug recess area before removing the spark plug. Failure to do so could
result in engine damage because of dirt or foreign material entering the cylinder head, or
by the contamination of the cylinder head threads. The contaminated threads may prevent
the proper seating of the new plug. Use a thread chaser to clean the threads of any
contamination.
3. Remove the spark plugs from the cylinder head. NOTE: Allow the engine to cool before
removing the spark plugs. Attempting to remove the spark plugs from a hot engine may
cause the plug threads to seize, causing damage to cylinder head threads.
4. Inspect the spark plugs.

INSTALLATION PROCEDURE

1_23_2012_5_11_30_pm.jpg

1. Measure the spark plug gap on the spark plugs to be installed. Compare the measurement
to the gap specifications. NOTE:
• Use only the spark plugs specified for use in the vehicle. Do not install spark
plugs that are either hotter or colder than those specified for the vehicle. Installing
spark plugs of another type can severely damage the engine.
• Check the gap of all new and reconditioned spark plugs before installation. The
pre-set gaps may have changed during handling. Use a round feeler gage to ensure
an accurate check. Installing the spark plugs with the wrong gap can cause poor
engine performance and may even damage the engine.
2. Install the spark plugs to the cylinder head. NOTE:
• Be sure that the spark plug threads smoothly into the cylinder head and the spark
plug is fully seated. Use a thread chaser, if necessary, to clean threads in the
cylinder head. Cross-threading or failing to fully seat the spark plug can cause
overheating of the plug, exhaust blow-by, or thread damage.
• Refer to Component Fastener Tightening Notice in Service Precautions.
Tighten the spark plugs to 18 N.m (13 lb ft).
3. Install the ignition coils.
