I have a Flint Hawken with the new lock and after about 5-6 shots I fail to get a fire at all. I am cleaning with alcohol, the frizen, pan and flint. I wipe dry. After a while it starts back working. Maybe do not wipe the flint and frizen with alcohol or what. I am not getting a flash in the pan at all. It is simply not getting sparks. The new lock is not damaging the flints, so that is not the problem. I am using TC flints. Help me, please
