Now that the pushrod is bent.there is TOO MUCH clearance between the valve and the rocker arm, resulting in the "ticking". With the valve "floating" to the open position and the pushrod perched on the edge of the rocker arm cup.the piston would have struck the valve and the resulting blow could have bent a pushrod. This could have occurred when the engine sped up "ungoverned" and "floated" the valves, allowing a pushrod to partially escape from a rocker arm. Another cause of this noise (based on the high RPM info) would be a bent pushrod. If this is the case and the screw is dislodged again, it will further chew up the insides of the combustion chamber and cylinder. One cause could be that one of the screws that held the choke "butterfly" in place has been embedded into either the piston crown, or into the cylinder head, and is producing a slight tap each time the piston reaches TDC. You must understand that you should not run this engine further until you determine just what is causing the "tick". ![]() You need to post the engine numbers (MODEL # and TYPE #) so we can view the IPL for your engine. You need to address the "ticking" sound, and quickly too. "Does pressure lubrication mean Briggs has an oil pump?" Well, yes."pressure lubrication" DOES mean there is an oil pump.
