Not really sure.
I mentioned that I drilled the exhaust breather. It was the transfer port cover, not the exhaust cover.
On the 1969 carb manifold, there is an oil breather tube that comes off and goes to the transfer port cover on the side, and from there, it exits into the leg. I do know they changed a few things with that part of it.
I’m just not sure why it’s a bit different under the reeds.
I don’t think it’s gonna make a difference, but I just want to make sure that it wasn’t for oiling or something of that nature.
