When I was wrenching at a Honda dealership I would set the valves (cold of course) and then start the engine and warm it up so it'd idle smoothly. Then I'd set the idle speed (to set the ignition timing) and set the dwell. I'd avoid working on a HOT engine but it'd be 'warmed up'. I have a 'timing window' that screws into the engine block... on the top near where the fuel filter is... so I could see the timing marks. I would spray some contact cleaner onto a rag and clean off the flywheel where the marks were and then paint them with some VERY RED fingernail polish. After that was done then I would set the carb sync and the fuel screws. The engine is supposed to be warmed up for carb adjustments. After that was all done I'd reset the idle. Depending on how off the timing was, how out the carbs were and how bad the fuel screws were out of adjustment I would sometimes have to reset the idle speed several times because idle speedcan be effected by all these adjustments.
Good luck.
