I put an injector in and you are right the o ring sits above there. I do not have a welder. I was looking into getting the flux welder at Eastwood but I am out of cash. I thought about an epoxy of some sort?????
I was reading in the how to porting guide that he just made it even with the rest of the port so that is what I was doing.I should have known better than to go too low there!!
