It's been 2 months since I sent my magneto back to the rebuilder (for the 3rd time). His armature guy found a short in the winding. I got word it's being sent back... finally. In the interim I picked up another piece of jewelry for the pre-unit. Jon Liddle in the UK casts these finned carb tops. When I saw them I had to have a set. They are a perfect fit and look fantastic!
