    I have a model 1950 with the same problem. I did the same things, replaced plug and ignition module. I put a screw driver in the plug cord cap and get a small spark to the head. When I put the plug in the cord and grounded to the head, I get nothing. I've set the gap of the module to the flywheel anywhere from flush to full gap to a cards gap with still no spark out of the plug. Could the magnets have lost their magnetism?

I had the same problem on a P3416 saw. I had a new Champion plug and coil installed. I tested the plug by removing it and plugging it in the coil wire and ground the end of the plug on the engine block. It did not spark so I bought another plug. This one fired but it was real weak so I loosen the coil and slipped a piece of light folder paper between the coil and magnets and tighten the bolts. Got a better spark and got it to run.

Installed 2 new starting coils, but still won't fire. Get only little spark. Has new spark plug. What else could be wrong?

Use a thin business card for a module gap gauge. Rotate the flywheel magnets under the ignition module, insert the card into the gap, loosen the module screws and allow it to contact the magnets. Tighten the screws again, and rotate the flywheel to remove the card. Make sure the plug has 0.020" gap. You should have plenty of fire. If not, the flywheel magnets may have gotten weak, or the ignition switch is partially grounded out. Hope this helps!

Poulan 295 model chainsaw/ won't start, no spark

Start first with a fresh spark plug set at 0.020" gap. Make sure ignition switch is on. If still nothing, remove the cover from the flywheel. Set the ignition module gap by using a thin business card between the module poles and the flywheel magnets. Loosen the mounting screws, let the module contact the magnets, and re-tighten the screws. Turn the flywheel to remove the card, then rotate the flywheel on full turn checking that the gap doesn't close-up any further. Check for spark again--if still nothing, remove the ignition switch wire from the ignition module. Check for spark--if spark now occurs, check the condition of the ignition switch or the connecting wire may be grounding out somewhere in between. If still nothing, replace the ignition module. Hope this helps!

Pro 42CC 2 Cycle Chainsaw, 18": how does this module work, what is the circutry ?"...

If you are speaking of the ignition module, the flywheel magnets induce a high voltage from an internal coil through a diode and into a capacitor and then the magnet position controls a transistor that discharges the capacitor into the ignition primary coil and that induces spark voltage into the ignition secondary coil which fires the plug. It requires several revolutions of the flywheel to charge the capacitor and why it takes several pulls of the starter to get the plug to fire regularly. That's a lot of action inside such a small package! Hope this helps!

I replaceed spark plug,and still on spark. Whats next? (poulan 4218) chainsaw

Remove the flywheel side cover to expose the flywheel and ignition module. Check the flywheel magnets to ignition module gap with a thin business card for a gauge. If ok, remove the grounding wire that goes to the ignition switch and try for spark again. If still nothing, it's new module time. If removing the grounding wire got it to spark, replace the ignition switch or perhaps the grounding wire has shorted out on it's way to the ignition switch. Hope this helps!

Poulan saw wont start has spark and fuel

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.

No spark from spark plug
