I'm just wondering if there's enough room on top of the head to drill and tap threads for a decompression valve like some mopeds used to use... Maybe try looking up decomp valves on treatland's site , ebay, or aliexpress to see if anyone makes a really small one that could fit on a CAG head.
If it wasn't a one piece jug/head I would consider it.

Yeah these cags have serious compression for their size. I had a $500 Stihl chainsaw that pulled easier than these suckers.

@ Intrepid: A DeWalt 18V might be strong enough to turn it over but I doubt anything less would do it without gear reduction.
