I have a Kohler K582s engine and when you try and to go to full throttle it acts like its cutting out and doesn't want to run very well. I checked both the spark plugs, they were fowled so I cleaned them off. I tested both of the spark plug wires and they both read the same. It has an electronic coil and points so I adjusted the points and it seemed to help it a little bit. I was timing by what it said in the manual and adjusted the timing with the governor and I ran out of room to turn it. I did a compression test and both were at 130 psi, what the book said they should be at. I removed the plug on top and I can see the bevel gear in the hole when the DC is at the top in the hole like the book says. I put a spark tester on both of the wires and it was firing, but could the coil be weak for it to idle and not go to full throttle?

Are the plugs carbon fouled or oil fouled? Makes a big difference as to what the problem may be. What do the points look like? What is the point gap set are, should be set at .020. When were the points and condenser last changed? What spark plug are you using? If the ignition system components are no longer in good shape and properly set, they could be the cause of your problem. If it came into the shop I would be going through all these components.
The spark plugs were carbon fouled and cleaned them up, I thing they said 216 on them if I remember right. Points didn't look too bad. Set them at .020". Why cant I get it to line up in the sight window when I use my timing light like it says in the service manual? I run out of adjustment. What should the coil test at?

Everybody thinks that .020 is the point gap on Kohler engines. .020 is the starting gap and then can vary by where the timings marks line up. You adjust the gap to get the timing mark to show up with the timing light. End setting could be from .014-.026
Are you using the correct timing mark. Seem to remember that there are two marks. One for timing and the other for TDC.
