karl, you are the one with the equipment. iFixit would have to try and get one and then spend more time and money in taking it apart and trying to figure it out. Why not do as @geirandersen is suggesting and lets see if the community can not figure it out. iFixit really can't do teardowns on every device out there. I am sure they would like to, but that is why they have this great community.

Since you have no spark you do want to go ahead and check the ignition coil etc. Here is the [document|28549] service manual that will help with the troubleshooting. @geirandersen is the small engine guru on here and can most likely guide you from here on.
