50cc Vibe 2007 in Australia.

[locallawoff]

Gidday All.I have a 2007 50cc Vibe and having trouble starting it.I have cleaned the Carby 3 times and set the air screw to the manual specs.I can start it in the mornings but cant start it in the afternoon.The autostart thingy is OK as per the tests.There is spark at the spark plug but dosnt look right.When I try to start it the motor turns OK but it seems too far advanced.I was wondering if the CDI could be faulty and telling it to fire at the wrong time.

Hi, have you tried with a fresh spark plug first? They cost less than a new CDI. Your old spark plug might look wrong because of changing the screw settings around. If you could get your hands on a new spark plug it might help with the troubleshooting. You might want to try that before looking at the CDI. Good luck.

Gidday,Brand new plug.  O Woe is me.

Sorry you're having troubles with your scoot. Maybe I misunderstood. What "doesn't look right"??

Try unplugging the CDI and then plug it back in.

This will reset the cdi and might help if the cdi is the problem.

Gidday again,When I turn the motor over to test the spark to me the spark is almost continuous compared to revs of the starter.Thanks

[Rianna]

I'm still not quite sure I understand. (Sorry) Do you mean like it's arcing or there is a connection that is off maybe?

[locallawoff]

Gidday again,I will try to explain the problem.I removed the spark plug and connected the HT lead to check spark.When I wind the motor over and watch the plug for a spark the colour of the spark is very dull and almost continuous compared to the revs of the motor.When winding the motor over with the plug in trying to start the scoot it winds over no problems then it reaches a point that the motor seems to fire at a point when the piston is on its way up the cylinder ie too far advanced which it makes me think it is the CDI as it controls the firing sequence and timing .I hope this may help my problem.Thanks

if your spark isnt a nice, pretty blue, you may have found your issue.. i know there are some cheap race cdi on ebay cheap........anyway you can check your numbers vs the manual???

[locallawoff]

Gidday,I bought the scoot at a garage sale for $100.It is a 2007 model.The previous owner stuffed the starter motor and the kick start gear trying to get it to go.New starter and gear fitted so now trying to get it running.Also fitted a new battery.Parts in Australia hard to get so GO Ebay.When the CDI arrives I get back to all.Thanks

Hi, locallawoff. I haven't been able to find a manual online for your scoot yet. But I did come across this video on youtube and there may be others on youtube as well. Those folks that have the same scoot as you may know where to find a manual. Good luck.

[locallawoff]

Gidday,I do have a manual which I got off Ebay.It came on CD and I printed what I wanted.Thanks for that.

[Rianna]

So glad it was on eBay. Good luck and let us know how it goes!

Hi again, locallawoff, I was looking in my manual (Agility 50) for some things earlier today and I saw these troubleshooting things and thought I'd post it for you.

Weak or no spark
Faulty spark plug
Fouled spark plug
Faulty CDI unit
Faulty pulser coil
Broken or shorted ignition coil
Broken or shorted high-tension wire
Faulty ignition switch/coil

Incorrect timing
Faulty CDI unit
Faulty pulser coil

The CDI unit is not adjustable. If the
ignition timing is incorrect, inspect the
CDI unit, pulser coil and A.C. generator
and replace any faulty parts.
