I keep a dedicated long bit with the tip ground off of it. That way it doesn’t drill a hole, but still augers out the dirt. I even run it in the hole in the side. I only blow air from the side to blow all the crap out the top. Use a bit the size of the side hole so its not so small as to break easily
On the sealing of the two piece gearcases a couple things I notice. I have quit using 847 adhesive. Started using 3M applique cement instead. More aggressive & dries quicker. Somebody posted that bulletin about sealing tips and they only put adhesive in a few {4} I believe places. I only put enough to hold the spaghetti seal in place. You do need the sealer at the rear for the junction with the bearing hub!
The other thing I think makes a difference is the orange spaghetti seal vs black. The black seems to be smaller in diameter or has a softer durometer?
Since the compression of this seal is really all that does the sealing (not gluing it) I want the best seal. Just a few of my ideas.
