All of the lawnmower formulated oils are high zinc. So Briggs, Kawasaki, Honda, Kohler oils are high zinc, along with the aftermarket oils sold by Stens, and Kinetix oils, The Rotella gas rated oils may not be high zinc but the diesel rated oils are. Are they needed. Not really.

New valve will still have to be lapped into the valve seats or the seats recut. And then the valve stems will need to be grind off to set the proper clearances.

Is the grass not being cut at all on those strips, or is it being cut but not the same height as the outside blades.

I have a customer on his third pump. Typical symptom is one wheel will start to slow down and not pull when hot. And then will reach a point that it doesn't pull at all. And it is always the right pump that fails. The pump and mating surface will both be scored. And repair parts are not...

Being that age of engine when was the valves regrind/lapped and the clearance reset. The old L series Briggs engines will wear the face of the valves to the point that will float the valves.

And if the OP has the dual pump he better be sitting down and prevented from fainting when he sees the price of that pump.

Very possible.

My suspicions are that it failed from lack of lube and when one rod broke it interferred and broke the second rod. Or they both broke from lack of lube and both seized and broke about the same time.

Take the valve cover back of and take the plug out. Now turn the flywheel by hand and watch the bottom valve which is the intake. As you turn the engine the intake valve will close and then should bump open slightly just before TDC. If that bump doesn't happen then that would indicate that...

Several factors can contribute to engine noise and the muffler is only one aspect. The cooling fan design can increase noise as well as the engine ducting. Then depending on if the internal gears are straight cut or helical can all effect how loud the engine is.

I suspect that is what he is referring to And as you know a weak battery on Kohler can cause the starter to turn but not enough to kick the gear up the worm drive.

And you looked at everything except the a poor battery connection or a failing battery. The chattering is normally a sign of the voltage dropping below a point that keeps the starter solenoid engaged and then when the solenoid temporary disengages the voltage rises re-engaging the starter solenoid.

I think it is a level point. There is no really good way of knowing if it is doing damage or not. Only way that would be proven is if somebody oiled one part on their mower and left the same part on the same mower dry and see if there is a major difference. And if that part lasted longer was...

If you previously used Lithium soap based grease it will not be compatible with the Polyurea.
