JD175 with 14HP Kawasaki Engine

slim · Jun 2, 2008

I recently picked up a JD175 with a 14 HP Kawasaki engine. It's been in the family since new. It has been sitting up for approximately 2 years but was running when put up.
The problem. It cranks hard but when cranked runs until it's hot. Then it loses power and misses. If cut off when hot it will not start until it cools off. If not cold it will bog down and die. When trying to crank when hot it will backfire badly.

At least 10 years ago it acted similarly but would not crank at all. At that time the Ignition Coil was replaced which fixed the problem.

The question is, would you start at the Ignition Coil (AM101065) or would you start with the Igniter (AM131398)? I'm pretty sure that it's one or the other and I can replace both with online parts cheaper than I can take it into Deere and have them fix it.

Thanks

Replace the ignition module and coil together.
What happens is a fouled plug which shorts the plug and overheats both the coil and module.
What fouls the plug is either a dirty aircleaner. Or more likely the operator which has inadvertently been running the mower with the throttle pushed all the way ahead into the choke region.
The operator needs to lift the hood and watch and learn to feel when the engine is at wide open throttle but off the starting choke "notch".
I"ve seen tractors in perfect tune get parked by an operator who has it sputtering over rich and under powered. In 99.99% of cases the operator has never seen or read the operator"s manual.

I have owned a 175 since new. Mine did what you say as did most of them. Many people traded them or junked them with the idea they were a lemmon. Deere actually had a recall campaign which some engine cowling was changed which is what was done to mine and it has worked wonderfully ever since. No $ charge either because of warranty. Probably close to 10 years ago now. The original cowling kept to much heat in thus vaporizing the fuel.Some of them you see where they have been hacked to serve the same purpose. This is one time you may want to consult Deere since it was a known problem in that model.Side note . They also had a starting problem which led people to think the electric starter was bad or the battery was weak. Neither is the case . I do not remember what the solution was but it is in the electrical circuit somewhere. Deere is also aware of this. When I complained about it they knew instantly how to fix it because of all of them being that way after a certain age.

I understand what you are saying but I my mother was the one who ran the machine. It always had a new air filter installed each year, in fact the one in there now is almost perfectly clean. And she definitely did not over-rev the engine. In fact she "putted" around the yard.

The machine was serviced and then run a couple of times before she parked it and started hiring her yard done. Oh, and we do have the original operators manual too but never bought the service and parts books.

So you would replace both parts? I know it probably needs a plug just from sitting and was going to replace it too. That's a cheap part.

Thanks

How can a shorted plug harm either the coil or the module? I can see how an open plug would make the coil build to maximum voltage and cause a lot of heat and eventual break down of the windings. Please explain.

Putt Putting around will foul a plug quicker than anything else.
My LX188, formerly owned by my parents, purchased when they bought a 500 series.
The twin Kawasaki suffered a burned out coil and module because my Mother would shove the throttle all the way up into the choke position. Start the engine and drive on oblivious to the missing, stuttering, chugging engine.

Now we know why you have a short fuse sometimes. LoL Your mother would probably slap you silly if you told her off. Dave

I have would replace the igniter. I did on mine and that is all it was. It would run till warm and quit. I mounted it on the frame instead of the engine to where it was a little cooler.

Did some more checking last night. I do have spark but it's a very weak orange colored spark. I tend to believe that it's the Ignition Coil so that's the first part I'm ordering along with a spark plug. I'll let you know the results.
