My carb inlets are cracked or so it appears. I'll try and take an image with my phone camera alas it had no flash so I need the day to light up a bit. Anyway, my engine runs fine. One test is to spray wd40 over the inlets, I did this with my tank unbolted , turned 180 degrees and sat on the seat. Improves access to the inlets. WD40 with the straw attachment and spray a little (1 second depress) over one of the inlets. See if the engine flutters. Repeat over the other inlets 1at a time. Flutters indicate a potential air leak. A vacuum gauge may also help diagnose but the carbs need to by syncd first ideally, mind you if there is an air leak then syncing would also be a challenge possibly.
For mixture tests I use a gunsons color tune. Great for pilot screw adjustments and diagnose fuel/air mixture dynamically through the rev ranges.
Hope this helps
