The jumper cables were not connected when it was running. In fact,I had the multi meter on my lap and was watching the voltage. It didn't drop. Could the pressure switch be acting up?

Most mowers are either set to kill the engine when the pressure drops or turn on a light but not both. You can try unplugging the pressure switch and see what happens.

Does the switch just go bad? Could something else be building up the oil pressure? I'll try unplugging it tomorrow.

Ok, I unplugged the pressure switch,volts at the battery were 10.5. Turned the key and it labored to turn over 1x put jumper cables on and was getting 13.5 at the battery. Turned key and the same thing,barely turn over . You can hear solenoid click. Jumped it at the starter and it started right up. I let it idle for 5 minutes, engaged the pot and mowed for 5 minutes, it started smelling hot and it died like before. Should I drive a stake through its heart and bury it!?

A went back and reread all the post to get a better feel for what is going on. You replaced the sump gasket. Now the engine is hard to turn over, has to be jump started to turn over the engine. Oil light is on.

I now suspect that you lost the oil pump driver that runs off of the camshaft when you had the sump off.

Take the engine back off and tip it up with the exhaust manifold facing up. Remove the three screws securing the oil pump cover and remove the oil pump. Is the driver present. It looks like a rod about 2 1/2 inches long with two flat areas on each end.

If the driver is missing we may be out of luck because of engine damage.

I know which part you mean. I'm pretty sure got it back in right. Is there any other way to check this without pulling the motor?

unfortunately you have to pull the motor to check it. If the engine was setting upside down when the sump was put on, that driver will slide out and fall into the engine. I tend to remove the oil pump, and then install the driver and pump after the sump is installed to prevent the driver from coming out.

Thank you very much for your help! I guess I'll tear it apart this weekend. I'll keep you updated on my progress!

Happy Saturday! Update...I pulled the motor and the pump shaft is where it's supposed to be.i did notice a couple of things though. It appears that I have oil leaking in the area of BOTH cylinder/valve gasket areas. It also looked like left side(facing the front of the mower) exhaust pipe was getting hotter than the other side. Suggestions?

Several things can effect running of the engine.. The difference in temperature can be related to spark, compression, fuel ( meaning one jet in carb clogged in two jet carbs) If they gaskets for the valve covers are leaking would be a good time to check the valve clearance.

Most small engines don't create equal power from both cylinders. More like a 60/40 split. this is related to very complex things which are beyond most peoples understanding.
