The solenoid on the bottom of the carb is leaking and needs replaced. valve clearance is .004" cold... last thing change the oil and filter if it has one before you try to start it again...
You could post the motor model number and that would help a lot, you need to check for spark at the plug, this in most likely not a valve or piston issue, the timing is off or the magneto gap is too big.
