Thank you for the part number. I got that part number shortly after making this post. Chainsawr is sold out and I've been scouring eBay to no avail.The ignition coil part number you need is 504620019. You can usually snag some great deals on either new OEM parts or even reliable used ones on sites like eBay or Chainsawr. Honestly, going for the OEM option is a smart move if you want something that fits well and lasts
