RE: Club FOX!
Regarding the ceramic coating, Sig used to sell Norvel AX-40 for around $100 until Norvel went out of business, so Sig dropped the price to $75 for the AME (ball-bearing, 2-needle carb) and $60 for the BigMig (bushing, 1-needle valve with air-bleed carb). Sig still is selling what is left in their inventory, around 40 units left. I like that engine a lot. It is strange looking, but runs great. I don't know how it compares to the Fox engine since I haven't bought any Fox's yet. The ceramic lining in the Norvel is interesting since it does not have a liner, the piston is right on the cylinder, makes it lighter and better cooling.
But as I said before, I can't tell how durable it will be since I have only had it for 3 seasons.
