The valve clearance is set by grinding the faces if there is too much clearance or grinding the tip of the stem if there is too little.
If it is a OHV engine you can easily adjust the valves. Try going to the link below for a video that shows how to adjust the valves.
adjust valves at rocker nuts until all noise (clatter goes away then turn each adjuster 1/4 turn at a time .let the engin recover as it will run a bit rough . then turn again unti the adjuster has turned a full 360 degrees or one turn
add 4 quarts, start, check and adjust level.
YES !!! it is a close tolerance engin . if the timing belt snaps in drive mode the valves will bend .
It requires an engine scanner to set the timing on that year engine.
Camshaft will be broken and inlet/outlet valves will be damaged. engin must be rebuilt or replaced.
