Running rich when NOT under load

I checked the coil. I replaced the plug connector just in case that had a bad connection. I removed the ground wire, neither made any difference. I suppose it's time to replace the coil and see if that is the problem. I am confused about which coil I need to get, there are two listed for the FC540V engine.
Kawasaki part #21121-2069 which is John Deere part number AM109258,
Description: Ignition coil for use on single cylinder engines. The models it will fit is 260 265 325 with a FC540V AS15 engine, F525 with serial number above 007892, F710 with a FC540V engine type AS12, 38" commercial mower, 48 and 54" commercial mower with 17hp engine AS11 only and a model LX186 tractor.
and/or
Kawasaki part #21121-2085 which is John Deere part number AM121810,
Description: Ignition Coil that fits John Deere 265, GT262, GT275, with engine numbers of FC420V GS00, HS00, JS00, KS00, DS15, ES15, and FS15, F710 with engine numbers of FC420V DS12 ES12, 325 except engine number AS15, GS75, and HD75 with 17hp engines, and 48" and 54" commercial walk behinds with 17hp engines with DS11, ES11 and FS11 engines.
Neither of these say they are compatible with the FC540V-DS15, the first one just says it's compatible with the AS15 and the second one says it's compatible with the 325 engine except AS15, GS75 and HD75.
Based on this I am assuming I need the second one, AM121810 and of course I can't find this one under $95 and these are non returnable so I want to make absolutely sure I'm ordering the right one. I'm really going to be hating life if I shuck out a bill for that coil and that's not the problem.

High lighted in red does not include engine FC540V at all. I believe I gave you the correct part number of 21121-2069
You are looking for John Deere parts. It is not a John Deere engine it is a Kawasaki. Only look for the engine model number and you will find everything you need and lots of places selling them.

You've lost me Blaz, I thought part #21121-2069 and part #AM109258 are the same item. One is the Kawasaki part # and the other is the John Deere part # depending on where you are looking up the part, but they are the same part. Same thing on part #21121-2085 and part #AM121810, the first is the Kawasaki part # and the second is the John Deere part # but that is the same part. I wasn't looking for "John Deere parts." I was looking for Kawasaki parts at the John Deere or TriGreen dealer. They do not use Kawasaki part numbers they use John Deere part numbers but they are still Kawasaki parts. If I'm way off on all of this then I need some serious schooling from you guys because you're destroying everything I thought that I knew, what already wasn't much!
You're right that highlighted text does not include the FC540V, it says it fits the John Deere 325 (except AS15, GS75 and HD75) which has the FC540V engine. To confirm that, this is what comes up when I search for the 21121-2085 coil:
Kawasaki 21121-2085
COIL-IGNITION
This part is compatible with the following machines:
•Kawasaki FC540V-DS13 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-DS16 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-ES13 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-ES16 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-FS13 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-FS16 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-GS03 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-GS16 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-HS03 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-JS03 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-JS16 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-KS03 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
•Kawasaki FC540V-LS03 - Kawasaki FC540V 4-Cycle Engine - ELECTRIC-EQUIPMENT
So it appears to me that both coils are for the FC540V, the -2069 coil is for the -AS15 engine only and the -2085 coil is for all other FC540V engines except the -AS15, -GS75 and -HD75. The problem is that my engine is a FC540V-DS15. The DS13 and DS16 are on that list but not the DS15. Of course its not on the list for the 21121-2069 coil either, only the FC540V-AS15 engine is listed for that coil.
I'm sorry to sound like I'm second guessing you but knowing that I can't return a $100 coil if it's the wrong one, I just want to be absolutely sure I'm getting the right one.

As for Repair Clinic, I've checked there for a coil. According to Repair Clinic, all three of the following coils are compatible with the FC540V-DS15: 21121-2069, 21121-2086 and 21121-2070. Just seems hard for me to believe I could pick any one of those three coils at random and any one of them would be good to go.

There are three different types of coils
1) plain coil get used with points or points eliminators
2) coils with multiple terminals used with engines that have an external ignition control module
3) coils with a chip in them , They have a single control terminal.
After that all 3 come is a range of sized to accomodate different sized flywheels
And some have a longer or shorter high tension lead.
fitted new a 5Hp coil will have a shorter HT lead that a 19Hp engine so it makes sense to use different coils but when it comes to replacement parts you can replace either of them with the longer HT lead model.
Add to that, various upgrades over the years and you end up with a lot of coils that will fit.
Some times the old model get deleted while other times it remains in production.
So you ring customer service & check that what you are offered will fit.
Stens & Rotary and Prime Line all do aftermarket coil replacements.
Lookup your coil on their web site and you will see that a single coil can replace 20 or more OEM numbers.

Been gone a week on vacation but it gave me some time to do some research. The coil I have is the 21121-2085 (or JD part # AM121810). It has been discontinued but there are still a fee out there for about $100. It appears that I can replace that coil with 21121-2086 which is about $40.
Before I order I want to be as sure as possible that the coil is bad. The spark tester seemed to indicate it is. I put an OHM meter on the coil and it read 13.01K OHM's. That seems very high and would lead me to believe the coil is bad. Does anyone have experience running an OHM test on a similar Kawi coil? If so, what does that number indicate?
