Today, I removed the four bolts for the Spinner Bulkhead and replaced them with the correct size bolts and then mounted the bulkhead. I set it on three washers to increase spacing a bit. Next, I attached the spinner to measure the exact distance from the spinner backplate to where the prop hub attaches to the flywheel/prop hub on the crank.
Just a little work today -- its a family day. Walk the dog, go to a movie etc.
