I have a GRRW halfstock flintlock that is not sparking very good. I'm not familiar with flintlocks and not sure what the problems may be. I think that the mainspring may not be strong enough because it's not flipping the frizzen forward when you fire it. The face of the frizzen is rough from the flint suggesting to me that it's soft. I would welcome any suggestions on how to make this lock spark better. It will not fire the gun more than 1 in 10 tries. I have tried a different flint that sparks good in a Chambers Ketland lock.
The first picture shows the fired state of the lock.
