Hi Matt. The screw near the top of the carb is the cover for the index mark on the slide body for setting the oil pump output rate correctly. When the indent in the side of the slide is in the middle of the hole you exposed, the marks on the oil pump body and moving arm should be alined. Does that make sense??? :-) It helps to have two people for this job!
The CDI units are one of the most reliable in the business, but there is nothing to say that yours might be one of the few to break. However, it is more common for CDI to just plain not work. You could try a coil off another bike. I have heard of one bike that lost the magnatisim from the flywheel. It is also possible that there is a shorting coil in the magneto as well. The only way to really diagnose these electrical problems without factory test gear is to swap with known good parts. It might also be a crank seal gone (assuming it is NOT an electrical fault). One way to test the crank seals involved pulling the barrel and piston, filling the crank chamber with petrol and seeing how fast it drains away. If the seals are good, then the level will only drop very very slowly with evaporation. Sorry I can't help more. Good luck!
Kind regards
