Pedersoli Bess Carbine Half Cock Question

[Louisk]

I'm still a bit on the backside of the learning curve for flintlocks. I shot my Bess Carbine for the first time last summer and ignition was a bit spotty. A new flint helped some, but when I took off the lock later I found a broken mainspring. Took it out shooting again after replacing the spring and still had a number of misfires. Moving the flint forward helped. I've looked at a few videos about installing the flint and they seem to show the flint very close to the frizzen in half cock. Half cock on my Bess still leaves a fair gap between the flint and frizzen (as seen in attached photo) Is that normal on this gun? Just thought I'd check that before messing more with different flints, etc. Thanks.
