Open Question

Homelite pro 4620c chainsaw not getting spark. I repaired with a new coil and noticed that the flywheel moves up and down slightly when I try to gap the coil against it. Is this normal or is a bearing (located on the backside of the flywheel) worn. Also is the gap between these two components about the width of a piece of sand paper? Any help would be appreciated.

Can't get a spark on Stihl 020 chainsaw. Tried another coil and switch module but still no spark

It is possible your flywheel has lost it's magnet strength, if you noticed it turn a blue. Can take off flywheel and replace with a good one. Or you can play with the gap on the magneto/coil, and insert a piece of paper between the coil and the flywheel magnets, to set for air gap.

No spark

Did you try grounding the plug against a clean metal surface of the saw and pull the starter rope. If you do not see a spark I would suspect the ignition coil.or magneto that the flywheel rotates around to create an elelectrical charge. Sometimes eith the magnet on the flywhell or coil can get rusty. Try cleaning them up with some light sandpaper. Just make sure you replace the coil with the proper gap between it and the flywheel. When testing for spark as described above make sure you are not touching any metal surface on the saw or you could get a shock.

Homelite Gas powered Trimmer will not start. Tried clean air filter....changed spark plug... no spark produced when removing plug from housing and pulling starter rope. Do I need a new ignition kit ? ...

The body of the spark plug has to be "grounded" to the metal on the engine when you remove it and test it. If you did it that way, OK. If there is no spark then (and it should be a nice blue color, not orange or yellow), the the "air-gap" between the ignition coil and the flywheel needs to be checked. Some disassembly is required to get to it as these parts are under the front engine cover. The air gap should be around .010" (or about the thickness of a standard business card). If the gap is too wide, the spark will be weak. If the gap is too close, the legs of the ignition coil may slightly rub on the flywheel. If you indeed have no spark, after properly testing, then check the air-gap.
If this is a fuel related issue, post back and we will address that as well.

It's about Husqvarna 345 chainsaw. I would like to know the resistance value between spark plug wire and blue wire from ignition coil, and between spark plug wire and the ground and finally resistance...

The easiest way to test is on the machine. Remove the ignition switch wire from the module coil. Check the pole gaps of the module by inserting a thin business card into the gaps after turning the flywheel magnets under the module. Loosen the module mounting screws to allow the module to contact the magnets, tighten the screws, and turn the flywheel slightly to release the card. Turn the flywheel one full turn to make sure the gaps don't close up further. Use a fresh spark plug gapped at 0.020" and try for spark. If nothing, replace the module. This gets around measuring resistances while trying to evaluate the module. Hope this helps!

No spark at the spark plug

Try this, if no spark replace the spark plug first(<$5) and retry.
It checks every part of the ignition system.
Ignition Coil Test by
You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You do not have to bend up the electrode.

Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when the flywheel is rotated.

Homelite/ (authorized parts supplier) - Agree; Choose “Product Line”; “Select OEM” & “Select Catalog” both to “Homelite Consumer Products”. A drop down list appears; self explanatory from here.
The numbers Homelite & Ryobi use do not match the numbers everyone posts. A careful inspection of your saw should find something that matches.

Thank You for using FixYa.

Chainsaw won't start when warmed up

Coil is possible, change the plug (cheap insurance) and try it. If problem persists try this shortly after it quits.

An index or business card is good for gap tool. Remove the plug, rotate until magnetic attraction pulls coil and card tight to flywheel, then tighten coil screws. Rotate flywheel until magnetic attraction eases, remove card, rotate a couple of revolutions and ensure nothing drags or contacts flywheel.

Homies are bad for clogged fuel vents too. When it begins to sputter roll it onto side and loosen fuel cap. If ti smooths out and runs properly it has a clogged vent. HTH

What is tolarance between flywheel and pickup coil husq model 40

First, try to move the flywheel end of the crankshaft up and down to check for bearing play. If it seems tight, turn the magnets just under the coil and use a piece of light card stock between the coil and magnets, rock the flywheel slightly, and tighten the coil screws. Rotate the flywheel somewhat to clear the card stock out of the gap. Turn the flywheel one revolution to make sure there is no metal to metal contact. Check for spark.
