You can see the groove on the tooth on the right, all the teeth are like this... I cant remember if it came like this or not, my guess is not...
How often should the bronze gear be replaced?

Should be a pre-season check item, never hurts to have a spare either.
It better NOT have come like that, and if I'm seeing the pic right, you have 2 problems. The teeth are not meshing deep enough in the tooth root (dist shaft is too far away from the cam gear), and the distributor gear is riding too high.
X2 on every year,
has anybody tried one of those composite ones???
Sounds like i need a new gear? I've run this gear two seasons now, really only one season because the first season i only got to run it for two trips.
If it has the o-ring in it, no need for the gasket on top.
Just a thought to add, have you checked how much oil pump shaft engagement you have? That's where I would panic, it looks to me like the gear is wearing like the either the shimming is off or dizzy in shallow (adjustable?) may want to check your oil pump for drag also...Those gears normally wear in and develop a pattern, that looks extreme to me, could be the pic though...
Not sure about the o-ring, where would it be? I don't think i have one, I'll have to check.
The dist isn't adjustable, i pulled the gear pin today to turn the shaft 180* to lock it out. I don't see how i could lower the gear, the pin on the shaft isn't adjustable, or maybe there's a gear i can buy that will lower it a bit? It could be my manifold i suppose too, my manifold fits the dist tight, maybe it's a bit thick too?
They were talking about an adjuxtable collar Billet Dist. Try a thinner gasket. I don't see anything wrong with the gear though. But then again, I don't have a new one in front of me to compare to. Go to the store with it and look at the new gears. Do you have a tall deck? If so, It will be too high with a standard non adjustable collar dist. The manifold could be machined down to get the dist lower like a non tall deck like they used to do in the old days or you could get the adjustable collar dist from MSD. Just a couple things to look into.

It almost looks like it was machined that way. Like already said, I'd take a look at a new one first.
thats normal wear, you could still run that for a while. i get about 1.5 - 2 seasons out of mine
I am running a composite gear on my dizzy. Thats normal wear for the bronze gear. Replace every season or so. It does look as though the dizzy is riding a little high though.
FYI, You can get a cam with a cast gear on it and not mess with the bronze gears...
