BOLTED RIGHT IN
Typical part from Replacement in that it fits perfectly and bolts right in. I've been doing business with eReplacementParts.com for a long time and have never been disappointed with any of the replacement parts I get from them. And the same applies here with this part.q

Tools Used

Parts Used
1. Remove all covers on trimmer motor. This includes the screws that hold the pull start reel to the case
2. Disconnect the two wires for the remote stop switch.
3. Remove the two screws that hold the magneto coil to the engine. Remember how close the old pickups are to the fly wheel. This is very important in that if this adjustment is wrong on the new installation, the motor will not fire.
4. Swap out the old coil with the new one threading the screws into the elongated holes in the coil only slightly tightening the screws.
5. Adjust space between the pickups and the flywheel.
6. Tighten screws on coil mount.
7. Reconnect remote stop wires.
8. Reassembly the case making sure that you properly align the pull start reel with the case. Misalignment will not allow the pull start rope to deploy.
Once assembled, attempt to start trimmer. If no spark, check alignment of the coil to flywheel.

I toke the case apart removing the four screws on the front of the machine disconnecting the shut off wire, for me the most important is to set the gap of the magnet to the coil I used a piece of very thing strip of plastic from water bottle to set the gap and it works.I also separated the screws on the order I was taking off so I don’t get confuse as I installing back.

I had to remove the motor from the housing and disconnect it from the shaft. Once this was done I removed the ignition module and replaced it with the new one. Then I space the distance between the flywheel and ignition at 0.014, I then put it all back together.
