I cant tell if they have drilled through and pushed down the cap or all the way down into the actual a/f screw. Not sure if I should drill further to try and access and replace the screw or what I'm really even looking at here.
Any Thoughts?

No matter which method you use be very careful because the metal is soft and you will go through it quickly. If you go too deep you will damage the needle jet head because it is soft brass. I learned this the hard way.
Haha for a second there I thought you were claiming to be the previous owner of my bike.....I had so many questions(and choice words) until I re-read that a couple of times.Herb wrote: ↑Thu Aug 26, 2021 10:40 amI'm the one I messed up it wasn't quite that bad I was able to get in and back out the mixture screw and get it all the way out. Then I went in then I took it and use the Dremel smooth the top off and recut the slot with one of the Dremel grinding disc. I reused the needle and it worked just fine.
Actually you did a Jim-Dandy Job with your Picture! Both Navigator and I spotted the Cap Right Away.Aequitas4 wrote: ↑Thu Aug 26, 2021 4:50 pmThe picture may have not done it justice. I already cleaned out the hole as best I could with carb cleaner and PB blaster. I have had both carbs off the bike to fully clean out each orifice and install a fuel filter as many of the tiny channels were plugged. I added pod filters as well. When I saw the bike had drag pipes and the Dyna 3000 ignition I assumed it should have had bigger jets but when I pulled them all out many of the numbers were unreadable. So I took the advice of the people on this board and since I didnt know the sizes I replaced them to be sure (been lurking on here a while now). I used the factory pro 3.0 kit and have used the 165 in the rear and the 155 in the front for the mains. Both new pilot jets and new needles were installed on the 3rd clip from the top.
It runs pretty well after the carb and throttle syncing at idle and mid throttle so my thought was if it was running pretty well right now that I wouldnt try to get to the a/f screw on the rear carb due to the risk of ruining the carb. After seeing some of the responses on this forum I'm planning on trying it tonight.
One other thing - if that IS the cap pushed in on the idle mixture screw....and you get it out...pay careful attention to whether it may have damaged the threads in the port. The needle is very soft and it you try and force it out through damaged threads you will more than likely ruin the screwdriver slot and possibly jam the needle in the port.Aequitas4 wrote: ↑Thu Aug 26, 2021 4:50 pm

However, even though the Enlarged Hole you just made did nothing to those Idle Adjustment Screw Threads. From what it appears, there still might be remnants of the Cap in there. In looking at the Outside Edge of the Drilled Hole, I think there is some of it left inside. I can't tell for sure if the drilling messed up the Slotted Head, but it appears it might not be damaged at all. (you can see it peeking out from under the Cap Remnants,...right in the Center of the Hole.).....One other thing - if that IS the cap pushed in on the idle mixture screw....and you get it out...pay careful attention to whether it may have damaged the threads in the port.
Are you guys looking at different pics? I can't see any of the screw showing - neither can the guy with the carb right in front of him.
