There is a company in Texas that still supplies many if not all parts for these engines, and may even offer completely rebuilt engines as well. R&D Aeronautical Engineering Co Inc. This guy is out of Caddo Texas 900-527-2006 They have a manual of sorts, and a printed parts list that are well worth having. Also search the net for Skeet Wynans, who flys a Hummelbird behind one of these. There's some pretty good YouTube clips of him at Copperstate

I need parts for a 4318, 72 hp McCulloch engine. Mag and prop hub would be good for a start.
