Answer
You paid $500 dollars for a used lawn mower. you can buy a brand new one at sears for 300?
Your probably paid for a $500 pos that was broken in the first place. Yet at this point you became a sucker, not only did you buy as is, You can't get your money back the Guy you bought it from, he just has to say it ran fine when he sold it to you.
Lesson here do your home work first, check prices at stores for the same brand before purchase
You could have got the same lawn mower brand new for less? Why would you buy a product that you have no history of? Now your out 500 plus cost for repairs or outright replacement.
Hope that helps

Answer
If the battery test good and all of the connections are good 12 volt source, check the valves in both overhead valve or in block style valve. Meaning, an overhead valve has a head with valves in it that you can take off, push rods, and adjustable rocker arms ( the valves are not contained with in the block). You should also check them on a valve inblock style on some series and brands ( ex. if it is like a k series Kohler they have adjustable tappets in them that have a clearance that needs to be set). I forgot to mention this style of motor contain the valve in the engine block You can tell by the head just being flat and just having spark plug hole and no moving parts in it. If it is a valve in block style or overhead, and all other conditions are met valves set properly,no electrical problems. This could maybe have a compression release problem. There is a spring and a lift pin on the camshaft that releases compression from the piston chamber. It is on the cam shaft and through cintrifigal force allows weights through turning rpm to move a pin and in turn allow the valve to go to the open position allowing compression to leak down and not dead head while starting so it can be turned over easier. After the engine starts the weights fall back in and the release is no longer holding the valve open and the valve tran operates normally. Usually if you put a charger on it will start fine. With this problem the starter has unlimited amperage ( whatever the charger is usually 300-600 amps if it a big one) to turn that motor over. Most mower batterys will carry a lot less cold cranking amps. Just remember that testing your cables can be tricky checking them with an ohm meter is a bad reading because if just one strand of the cable is touching you will get a good reading. Check the draw of the starter with an inductive pickup to see how many amps it is pulling if it is pulling just a few it is cable and connections or starter prob. If it is pulling a lot could be starter problems or it could be a compression problem because the starter is having to work double time to try and turn that motor since the cylinder is building up full compression. I have had the compression release in many cases cause a customer to buy a new starter, cables, and switch when he didn't need em. He put it on and it didn't make a difference. I am into diagnosing not spendin money. Hope I helped you diagnose it and I explained it so you could understand p.s Just dont want you to spend money on something you dont' need!
