I have been trying to start it with it hooked to a battery charger. It cranks good. All checks came out fine. It has spark just very weak. It has a new plug. I was thinking that the CDI must be bad, but it should just turn on and off the coils and not the intensity of the coils. It quit while riding and would not restart. It used to start everytime and then this one time it quit and thats it. Thanks for your help.
If you look closely you can barely see it. At first I didn't think it had spark, but then we saw it. Of course it was daylight, but It was very thin and faint.
Mine looks very weak and puny in the daylight too, although the scooter runs fine. I really do recommend you try it in a darker atmosphere, such as night, because as said it really is hard to see during the day. Also are you sure you checked simple things such as the air filter etc?
Are you sure you have good compression? Remove the spark plug and put 5-10 drops of oil (anything will work i use regular 30weight oil because i have a squirt bottle of it) down the spark plug hole, then crank the motor over for a few seconds with the sparkplug not in. Put the plug back in and try starting it if it runs you have bad compression.
I am not a mechanic, nor do I play one on TV. Actually my advice is probably worth slightly less than what you pay to view it.
Thank, I tried that too. I also tried priming the down the plug hole and still have no fire. I have good compression according to my gauge. It won't fire starting fluid so i assume its spark related.
