Hi all,
My 15 month old agility 125 suddenly won't start. The electric ignition is sounding just fine and there's air coming from the exhaust when I do, but something's gone completely a miss. The engine won't catch at all. Strange as it was running sweet as a nut up till now, but I turn it on next morning and I get this.
I've got a little tool set that came with it, not sure where the manual is at the moment but have heard its not that useful anyway.
So at the moment just trying to locate the spark plug. Contrary to what I've heard others say, I don't see a compartment infront of the seat that can be opened, in case it's in there. Need to get back on the road asap. Hoping this will be the problem.
Many thanks.

..pretzelz, there is a link to your Service Manual on the page above..Not the owner's manual that you get with your scoot...It's very helpful...
..there could be a number of causes for your problem..
..If you've used any gas from a can, there could be trash in your carburetor..
..could be the spark plug..
..could be the cdi or stator..
..get the manual, and you will surely be able to locate your plug...
..post back with some more info..
peace

Nothing new with Kymco...
Maybe electric choke?
Leave it for few days alone in dark, he ll be back....

Thanks very much for the link to the manuals. I had a look through some and couldn't find Agility 125 as such. Instead I found something called a B&W which looked reasonably similiar, and that said to taken the central front cover off. Well since I didn't see a cover at the front, I guess I'll have to take the whole thing off somehow. Does sound too accessable. Let's just hope it is behind that cover! :-\
-
Since you really don't know where the problem is yet it may be easiest to remove all the plastics, and give it all a good going over. It is easiest to remove the seat, and the tub underneath to get access to the spark plug. Don' bother looking at it just replace it, and let us know how it goes.
-
Thanks I shall attempt the spark plug tomorrow. Failing that though I think I'll have to take it to the dealer because I don't know how to do all the other things and this is my only transport at the moment so need it fixed fast.

We're all here to help pretzelz. Post away!

Does it even pop a little? Anything like trying to run? Have you checked the engine kill switch?
-
Along the same thought there are two fuses in the battery compartment. Check those out too!

pretzels...this is the direct link to your service manual...

Thanks, that service manual clarified things somewhat as was having alot of trouble locating which one was the spark plug cap, as they didn't show it in the picture with the cap on it. Now I'm stuck again, I've put the cylinder into the socket and put a screw driver through the cylinder to lever it round with force but it will not budge. Any more pressure and I'll bend the screw driver. Should I get out an old impact wrench I have somewhere and try that? I'm at this stage (see photo attached)
-
..make sure you're turning counter-clockwise, and i would not suggest using an impact....
-
Just be smart...
You know how to unscrew spark plug?
I think ur going in wrong way....
screwdriver must go up.....for that....
try to move socket wrench a little, its gonna give u space for screwdriver (little by little change positions)....
-
Success, used a socket wrench with 2 attachments onto the cylinder piece.
This is first time I've ever changed a spark plug.
So now I'm looking at the spark plug and wondering what sort of condition it is in and whether thats an indication of the problem.
-
just change it.....
-
While you've got the spark plug out, this is a good time to check to see if it is indeed sparking.
Insert the spark plug into the spark plug cap.
Make sure kill switch is in "run" position. And make sure all other cutoff switches are in run position -- side stand up switch? Brake lever pulled in.
Key on.
Rest the spark plug (inserted in the cap) against some metal part of the engine or frame. This will ground the plug.
Once all this is in place, hit the electric starter button and watch the spark plug for a spark at the electrode gap. If it does not spark, just try holding it more firmly against some metal part of the engine to insure good grounding.
If it sparks, your problem is elsewhere. If not, further diagnosis is required.

If interested, here's the low down on my frustrating day...
First thanks Hoolander for all the information. Unfortunately right now I'm not in a position to be able to do those things as a) I simply don't have the time (am finishing assignments for the last year of a postgrad course) and b) this is my only form of transport at the moment and as such need to get it fixed asap, which unfortunately means taking it to a shop. ...Had this happened any other time then I would have spent a while looking into all those other possibilities as I would like to become much more self reliant to fix things and troubleshoot them.
So, four and a half hours later and a cut finger, of trying to replace a spark plug, it's done. And unsuccessful.
I finally managed to get the old (15 month) spark plug out with the wrench socket. The end of it did look black. Not oily but definately black all round the tip of the thread. ...off to Halfords I went, bought the nearest one that was recommended to me (called a NGK C7HSA when the one recommended for agility 125 is apparently an CR7HSA - the guy said the R stands for resistive and won't make any difference)
Got home, put the new one in, wasn't too sure about how to secure the rubber cap back into the whole and within a few seconds had broken the cable off that feeds into this rubber cap. (as you'll see in the attached pictures).
While I was there holding a lead with just wires sticking out of it and the new spark plug in it's socket, I thought I would hold them together and try starting the moped. No luck, not even a spark.
I tried reputting the cable back into the rubber cap and plugging this back into the spark plug socket. Still no luck. (It was a case of screwing the exposed cable into the cap to connect that back up again)
Now unfortunately I'll have to take it to a shop, as I presume it wasn't the spark plug at fault, even though the old one was black. That means I'll be cycling across town for the next few days as I even find a gap to take it to the dealer (or my local car mecanic, wonder if he will do it?)
The attached pictures show my old spark plug and the cable that I had accidently snapped out of the rubber plug socket.
Still interested in your insight to the situation... perhaps there was something I still did wrong with regards to the new spark plug?
Thanks.

Same happened to me few months ago.
Got really mad at Kymco....
But i just tapped on receiver magnet at stator coil and spray some WD40 and kymco started like new....

..that shoulda knocked you on your ass..........
-
rather glad it didn't

The plug that came out looks like it has a nipple on the end where the one you replaced has a threaded end. Take the Nipp. off the Original plug, and put it on the new one. You are trying to jump 1/4" gap before a .30 gap thru a resistor plug

..couldn't tell if that was a nipple or just glare....hmmm...

Just wondering if this was ever resolved? I am doing the same thing on my scoot right now, with similar results. I'm trying to find the carb drain plug to make sure it is getting gas, but I am having trouble. Anybody have an idea? Do I have to take the carburetor off to get to it?
-
...carb drain slotted screw should be on the lower left front corner of the carb...
..need a flat-tipped screwdriver, and it's pretty tight...
