Cant find the problem with this Agility.

[wildwildip]

I have an Agility 125. It has always run fine, however in the middle of winter it started running rough, and now it wont start.

Battery is good, (Has tender on it)
Spark plug is brand new
New Fuel filter
Fuel had sea foam in it during storage
Clean oil.
Valves have been checked
Fuses are all good.
I even cleaned the jets on the bottom of the carb (removed bowl, which was all clean)

It will turn over but never start! Even with spraying carb cleaner into the intake as I hit the start button.

Gas tank is full, kill switch is on run.  

My only guess is maybe the timing is off, carb has an obstruction in it, or maybe the auto-choke device is no longer working.

What kill switch? Agility 125 does not have kill switch.

There is much simpler root cause - microswitch behind the brake levers that actuates the electric circuit, so you can turn the engine on.
Check them first.
A125 will not start if both fuses in the floorpanel are not intact. Once had a problem where both fuses LOOKED good but obviously one of them was faulty at the point where the wire touches the contact metal - so you could not see the breaking point. When I replaced it, it was OK. I would check that too.

Finally, check the auto choke, there is a procedure how to check it in the service manual.

It does in the United States. All two-wheeled vehicles sold new in the U.S. must have one -- and also NO switch to turn off the headlights (and turn indicators must be 16" apart, on-center, etc.)

6-7 years ago most scoots had light switch that could be turned off, then they stopped installing them.
For some reason, few years ago, these switches are again on scoots, so I can completely turn off the light both on P250 and A125.
P250 has kill switch, A125 does not.

No 50 cc scoot has kill switch here, most 125 do not either, almost everything above 125 cc does.

Have you remover the vacuum line to the petcock to test for fuel flow? Carb clean should have given at least an Umph of trying to start unless there is NO spark. have you checked to see if you do have spark?

Oh! ps. The micro switches mentioned will only prevent the starter motor from turning. For safety reasons they do not affect ignition.

The motor will turn over and spark.  (Pulled plug and it sparked just fine)  Also, BOTH fuses are in tact.  I could try replaceing them even though they both, visually, look fine.  And yes, it DOES have a kill switch, I can post a pic later.

I have not done that specifically however I have replaced the fuel filter, and drained the bowl.  Then turned it over several times and the fuel filter filled up and the carb bowl did as well.  Plus as I turn it over, I smell unburnt fuel coming out the exhaust. And spark is good. I know it is sparking, I pulled the plug out, put in into the boot and turned the scooter over while holding the plug near the frame.  A Good spark was produced.

Ok the other basic check would be compression. It is possible the jet picked up something, and leaned out the fuel mix. That would gradually run the rpm's down untill a no start. With a compression tester you should see a minimum of 100psi. If you don't have access to a tester the next best thing is to pull the cylinder, and inspect all the surfaces for melting or scoring. I found invisible holes on the dome of my piston that only showed on the underside, so take a CAREFUL look. This thread has some picts.   http://kymcoforum.com/index.php?topic=1759.msg10773#msg10773

Have you tried spraying some starter fluid in the intake.  If you have spark, it should at least sputter a few times with some starter fluid!  That is unless there is no compression!

I have done that.  No spark or firing at all.  I will check my compression this weekend, i already have the device that measures it. I hope it isnt something serious with my valves.  (Which I have checked, the gaps were correct and the chain, ect was all in good shape.)

I don't know what to tell you.  I hate to say it, but it doesn't sound good!

AWWW! Como'n shaka... It's just a scoot! How bad can it be???

[Shaka]

My guess is that if it has spark, but won't fire even with starter fluid, that it doesn't have compression.  The first thing I would do is check the timing and pull the head and check the valves.  There could even be a carbon deposit that has lodged in the valve seat preventing it from sealing.  I would almost be willing to bet that you're going to have to dig a little deeper into the engine itself to solve the problem!
