Look for a pinched/bare stop-switch wire (I assume that you don't have spark now). Also, check the ignition coil core gap to the flywheel magnets (I use card stock to set the gap). Make sure the plug wire was not damaged again.

Immediately after it stalls do this:
Ignition Coil Test
You may need to use a jumper wire between the threaded part of the plug and the cooling fins. You don’t have to bend up the electrode.
If spark good:
When it begins to stall loosen fuel cap if that fixes it fuel vent problem.
If spark and vent good it is most likely a fuel delivery problem. Check the fuel filter on the free end of a hose in fuel tank (manufacturer recommends an annual replacement). Check all fuel delivery lines especially at fittings and bends for cracks and holes. If those are good then the likely cause is internal parts of the carburetor.
Was this saw perhaps operated without oil mixed with the fuel?
· Remove the spark plug wire and plug.
· Remove the muffler, hold a light at the plug hole and inspect the cylinder through the exhaust port. Is it smooth and shiny or does it appear speckled with dull gray spots or smears?
· Pull the starter slowly, inspect the piston as it rises and falls. Is it a dull gray without scratches and gouges?
· Hold the light at the exhaust port and inspect the cylinder, above the exhaust port, through the spark plug hole. Is it shiny and smooth or speckled with gray spots or smears?
Any spots or smears on the cylinder or deep scratches and gouges in the piston indicate the saw was operated in a lean condition. Repair of this on a home owner quality saw often exceeds replacement cost. A repair estimate by the independent saw shop should be considered. HTH
This will even work on a Chinese McCulloch 3416. If this is a Mac it may be very difficult to find a repair shop willing to repair it.

Maybe a little cross threaded or swolen from contact with fuel.
Please verify this is your fuel cap. HTH

A thin business card is just right for setting the gap. Turn the magnets to be under the module poles, loosen the module screws and allow it to stick to the magnets. Tighten the screws, rotate the magnets away and remove the card. If the module is good it should make a snappy blue spark with a new plug. If rotating the flywheel through one revolution causes any core rubbing, the crankshaft may be bent or the flywheel may not be fully seated on the crank shaft. Don't run the engine until this problem is repaired. Hope this helps!

The spark should be blue in color not orange or white. A bluish ornage is ok. The easiest was to set the gap is to tear off the front and back of a match book cover tear it in half and place the 2 pieces between the module and the flywheel losen the module and let it slide against the match book cover. Tighten the mounting screws and then turn the flywheel to remove the match book cover. <- (Been doing this for 40 years!)
I suspect your problem may be fuel / carb related vs ignition.
However.... a bad spark plug will spark when removed and you have grounded the electrode end to the engine but will NOT work when you install it. Make sure you change the plug. (FYI I have seen new Champion mini plugs fail right out of the box.) I have had as many as 3 in a single NEW box of plugs fail.
Just for grins try adding a splash of gas into the spark plug hole or carb throat before you try and start it. If you get a momentary start you have carb / fuel supply problems.
If you discover you have carb / fuel problems just repsond and we can proceed with getting you going again. I will help you.
Thanks for Choosing FixYa
