kawa deere

I agree, it is something simple.

Thank you for everything.

I do not like to be a parts replacer. This may be an exception.

i checked tew's website. if the part number they sent you (if you bought it there) is 29-1039 that should be the correct one. it says it's the replacement for deere am109209.

if they sent you part #29-1038, that one has an internal ignitor and won't work.

can you post a pic of each one?
if i had pic ability, i'd post you a pic of each one.

I did cross am109209 on google at tew's site. I ordered 29 1039, but I cannot confirm that I received that #. I tossed the receipt and cleaned my email. Doesn't that suck.

But, there is no reason for them to sub a part, and the tests are the same with the new mag and the old.

I will call Mon and confirm the part #

okay. i'm dying to find out what's wrong.

if you find out, please post it. it might save people a lot of trouble.

i'll keep thinking on this one and see if i can come up with anything else.

eta...i'll check my deere and kawi manuals mon. and see if they have anything. i do know deere/kawi had some problems with bad ignitors (hence all the part # changes) but that was about 3 years ago.

kawa deere

At the moment, I'm doubting myself.

When I or you solve it, I will post

What are the odds of having two bad coils or two bad ignitors?

What are the odds of having a bad flywheel?

What am I overlooking?

kawa deere

so,

possibility of electronic ignition problem?

do you think possible or probable?

I could have fried it, but soft test does not show I did.




If you have a 2 cycle problem, I will return the favor.

My mechanics did not like to do 2 cycle, so, I got good at diagnosis of 2 cycle.

Hey Dennis,


I have read the same problem on this board, You might test both igniters as the chart below (pick your style).

Even though the igniter is new it's new aftermarket (Stens), That was deemed the problem on the other two engines I read about. Once a OEM (Kawi) igniter was installed spark was regained, I can't explain why but that was the fix for them.







Good Luck

i have run into bad out of the box ignitors but that was a few years ago when deere first changed part #'s.

i've also had coils and ignitors test good on the coil checker and with an ohmmeter but not work when installed. that's why i keep known good spares on hand from junk engines.

it's aggravating when you have a new part that's no good.

flywheels rarely go bad. when they do it's usually 'cause somebody hit the magnet when trying to remove it.

if you have access to a running engine, take the ignitor and coil off and try them on yours. don't forget the ignitor must be mounted/grounded to work.

i'd get another coil and ignitor preferably from deere and try that before getting a flywheel. it's expensive, but cheaper than a new flywheel.

the coil could be bad. remember the tecumseh factory coil problem of about 5 years ago? we got 10bad out of the box coils from them. their answer, "buy them from rotary until we fix the problem."

eta.. thanks for the offer on 2 stroke, but i avoid them like the plague. i let our 2 stroke specialist handle them.

Thanks for the help and return reply.

To refresh, the new coil is from Tulsa Engine Warehouse ( aftermarket).

The ignitor (electronic ignition) is original Deere AM131398 which is the current correct new part # for fc420 as10 (kawasaki engine #). I have also perforemd the test printed. The original ignitor tested the same resistance whether the - or + was on the connection. The new deere part tested correctly per this post. Of course these little critters test good, when bad sometimes. I had found this article, on the internet, before I installed --about 4 days ago. I also retested the ignitor after installing and after attempting to get fire on the mower. It still tested good.

I know the likelihod of having a bad ignitor is greater than the possibility of a bad flywheel magnet (never seen one go bad). There is no indication the magnet has been hit by a hammer. I tend to feel that it is one of the two though. The probability of the new coil being bad would be the least likely.

Thanks again. I believe I've worn this thread out. I'll have to load it and carry it to a dealer or buy at least another Deere ignitor.

Hi,
I just noticed something that I think is a problem with the kawa module, at least with the motor I have (fc420 as10). It is the location where the ignitor mounts. Rather than mounting to the engine block, it mounts to the engine cowling. A resistance in the ground can fry a ignitor or prevent it from working. This ground on the cowling (where the ignitor is screwed on) is dependent on other bolts to ground it to the motor. Give a mower 12 years of mowing and dust or rust builds between these connections and there is no fire.

I am out of the box but still in it on this one.

It is 100 degrees and humid in west Texas today and I will test this theory tommorrow.
