Hi,
I recently finished building a grubee skyhawk 66cc kit. I had a lot of trouble starting the engine at first, but after a week of trying I finally managed to get the motor to start, and it ran very well. The reason why it would not start at first was either the choke, or the idler screw (I adjusted both at the same time, and then it fired up). I started it up about 4 times in two days. and each time it would take about 20 minutes for the bike to start up, witch is certainly not normal. The next day I tried to start it and it would not start. I tried for an hour. I havent been able to get it to start since. I think it is a spark issue. Gas is getting into the motor (spark plug smells like gas) and there is compression. The stock spark plug sparks a little bit, just enough to see. I've seen videos and the spark seems to be much bigger. I just bought a new NGK plug and it hardly sparks at all, less than the stock plug! I am pretty sure it is a CDI issue, although I am not really sure. Any help would really be appreciated.
Thanks
