As clearances are reduced, the valves start to burn out slowly.. Cheers Feral Errol

Yeah I tried half a tank of unleaded the other day and noticed a bit of a rattle under load, maybe ill stick to leaded. The motor is standard and seems to be in perfect condition, carbies aside, so I dont really want to trash it. When you get valve seat recession and the motor dies, does it normally do it gracefully or do valves start hitting pistons etc?
