Always do an adjustment on a cold engine, remove the valve cover and gasket and the spark plug. Then position the piston at TDC. Use a feeler gauge to proper clearance specifications. Then adjust tightning mechanisms on the rocker arm until the drag is felt. Check or replace the valve cover.
If the push rod is bent or curved it is better to get it replaced by the company. Does your lawnmower still come under warranty? If yes, then this will not cost you anything at all. add a comment
