Puch rod come off roker arm - Briggs & Stratton Power Products 5,550 Watt Portable Generator #30241

Usually there is a reason why the rocker arm came off the push rod so you will need to check a few things before putting it back together. First make sure the push rod is not bent, if it is replace it, do not try to straighten it. Make sure the rocker arm stud did not loosen, if it did back out, re-tighten. If you're ready to put it back together, you will need to set the valve clearance between the rocker arm and the push rod. You will need to know the engine model number to get this clearance since it varies. Once you get the clearance values, make sure the piston is at TDC on a compression stroke and adjust the valves per the setting. In some rare instances, the valve can "stick" in the valve guide and this will cause excessive gap. However, usually when this occurs the engine will not start anyway. Hope this gets you in the right direction.
