Good old 4 cylinder, 16 valve Honda workhorse cruiser. First, get rid of the old fuel and put fresh in. Don't forget to drain off the carb float chambers. Assuming the bike has been outside, spray the coils/ leads/ plug caps with WD40 or equivalent and crank the engine. If still no good, pull the ignition leads off the plugs, put a known good plug into the plug cap and lay it against the cylinder block. rank the engine andlook for a spark across the plug's electrode gap. If a good spark is present, change the plugs. If there is no spark change the ignition lead and cap using motorcycle approved cap. If still no spark, check the contact breaker points for opening and closing. There should be a small spark here. If not present unclip the condenser. If spark present, change the condenser.
