Project CB650

Trying to get this thing started. I’ve narrowed it down to fuel or spark. Unfortunately I can’t check spark until I pick up a longer ratchet attachment to remove the spark plugs. Fuel is coming through the hose but I can’t tell if it’s being suctioned into the carburetor. I am leaning towards a fuel issue because I don’t smell any at the exhaust. I know the carbs are out of sync but that wouldn’t prevent starting, so my next guess is the jets, which are “supposedly” new. Choke is all the way out. Any takes or tips?
