Poulan magneto coil
Item arrived quickly. Installed in a few minutes, took a few more to properly adjust with feeler gauge. The spark plug cap had rubber flash inside which made it difficult to properly insert the plug, finally carved it out with a craft blade. Motor fired on first pull so replacement a success.

Easy, but lots of parts to remove to access it. I removed the old module, then installed the new one. I set the gap between the flywheel magnets and the module at 0.25 After changing the ignition module, engine started on 3rd pull. Excellent service from ereplacement. Will buy again.

1. Disassembled the cowling and removed the engine from the shaft.
2.Removed the damaged ignition module
3. Installed the replacement ignition module
3. I set the ignition gap between the ignition and flywheel magnets with a standard business card
4. Reassembled the engine and cowlings.
Removed the covers and got to the ignition module. Took the old one off and installed the new one. Put everything back and got it started. Worked well.
I had to disassemble all covers and separate motor from shaft not hard to do with a T-25 torx driver. Coil is easy to get to. When putting new coil on turn flywheel so magnets are in line with coil and use a business card to gap them. Then tighten the coil down.
The whole process took me about 40 minutes.
