I have (potentially) similar problems, did you solve yours?

Agility 50 / Re: (Almost) no spark / engine not runnign

And how can i check that there is actually gas going out of the carb? Gas ok till carb, pumped in, but as the spark seems dry i wonder if the gas is not flowing through

How can i check that the cdi get the correct pulse from the pulser coil? Supposedly measure the voltage over the pulser coil ive been told, but what should the reading be?

carb seems fine, however I have some questions to the auto bystarter. The manual specifies max 10 ohms between the terminals and my voltmeter reads 14 ohms - is this enough difference to mean anything?

Hmm, I'm still having problems..
Have tried with a new rectifier and different CDI - still no spark when start motor runs. With the other CDI, I hardly saw a spark at all. (With old CDI I see spark once after start motor has run)
Seems to me that the electrical setup is fine, have done pretty much all the checks I can think of (but not the start engine itself). Could it be something with the carburetor, chocke or something that also messes up the spark? The spark plug dont get soaked in gas, so might be some trouble in the carburetor - guess I'll have to work from that side now..
tips on what to look for is much appreciated. I have the Kymco manual

So, now I've checked the ignition coil and the pulser coil as described in the service manual. Ohms are all as they should.
Also tried to check the resistance in the CDI, but that was a little more challenging to replicate the values given in the manual - however the manual explicitly states the need to use some measurement devices I don't have -I just tried a normal multimeter.
Furthermore, I've checked that the battry does not drop in voltage when the starter engine is run, hence battery seems fine. Have however been adviced to try with a starter battery from a car, and might do so...
Any other ideas of what to check? Growing anxious it is the CDI, which a dealer quoted me 500 $.... Any ideas how to confirm the CDI is broken?
thanks.

« on: August 15, 2011, 09:51:07 PM »Are you not able to crank the engine over and use a meter to check power output is coming from the coil where it leads to the spark plug?Can do that and have a meter, could i Ask you to indicte where i find the coil and "how" to meter; what should thenreading be? Tnx
I had a similar problem. Turned out the power lead to the starter was loose and grounding out. Since that has been tightened down, has not been an issue.
Good luck.
Interesting, did you also notice that the sparks were not there steadily?
Btw tried with fully charged battery and new plug tonight, no prgress at all...

Agility 50 / (Almost) no spark / engine not runnign

Hi,
hope to get some advice on a technical issue:
Agility 50 cc, 4 stroke. 2008 I belive. ~2500 km
Issue:
Scooter always worked fine, but stopped when I was waiting at red last week. Did start again, but didn't run long (10 sec) . Just died /faded away - sounds like ignition problems. Tried again a few hrs later and could drive home (2 min), however almost stopped a few times.
Spark plug has never been replaced (getting a new todday). However afraid it will not be enough.
Have done a few checks:
(1) Gas OK till after the filter (Flows when trying to start, seems like there is a pump "pushing sequently")
(2) Spark plug a little black, but not bad
(3) plug gets wet when trying to start (some gas reaches the cyl)
(4) no spark when running start engine (only after start engine doesnt run anymore, that is, I see 2-3 sparks after the start engine doesnt pull the engine (it still goes a few rounds around) So no spark until the start engine doesnt draw from the battery.
Hypotheses:
(A) spark plug worn out ?
(B) CDI / Coil not working properly?
(C) battery needs charging ? (had no problem running the start engine in the start, however got slower)
A and C to be checed today w new plug and recharged battery, any ideas how to check B? Any other advice?
Thanks in advance.
