Kids was riding yesterday and thought they ran out of gas when it died.. topped off the gas and went to start and the solenoid just clicks as if the battery is dead. Voltage is good on the battery and all the fuses looked good so I tried to use the pull rope and it won' even budge.. could the engine seized or blown without making any kind of warning sounds? Just had the oil changed and it still looks fresh.. any ideas?

 

Take the plug out and check if the engine will then spin over. If it won't, something has seized. Not necessarily the piston or bearings. I had one that seized a camshaft (short of oil) but have had Hondas where something has come loose and jammed the alternator/flywheel.
