Part of the Lightspeed electronic ignition is a pair of sensors that tell the system the position of the crank. These sensors sit right behind the propellor and sense small magnets in a ring that was installed on my flywheel by lightspeed.
The trick is that these sensors need to be installed very precisely, and I had to drill my own mounting holes in the block to do this. And when I say I had to drill my own holes, I mean I had my buddy Jake come over and drill the holes for me!
The sensor brackets have features built into them to help you get everything lined up. They have little temporary feet that sit against the crank to position it properly in that direction, and it has a notch that gets aligned with the case split line. The difficulty comes in needing to drill and tap these holes when the crank flange is blocking your access. The way around this is to press the threaded bushings out of the crank flange, and actually drill and tap right thru the holes in the flange. It’s tight, but it can be done. (Unfortunately, I didn’t catch this part on video, but I do have a lot of pictures)
Once it was all drilled and tapped, the screws were installed with Loctite, a star washer, AND safety wire. I never want these screws coming undone!
I also finished up some final details on the cowl flap installation.
