What does it mean?
Right now, after switching out a 50cc bidalot for a 70cc malossi on my AV10, I can't get it to hold an Idle for the life of me, Thrown the jetting all over the place. I assumed that the electrical and everything was fine, because I never had any problems like this on the previous cylinder. I looked at the plug, and Its coming out pretty grey, what does this mean? I have heard it was electrical issues, but I have CDI. Can it be timing? I dunno I'm kinda stumped why it won't Idle.
