I know this has been talked about before but I am wanting to put timing advance on my 1985 ATC70. I have been looking at rotors with the mechanical advance built into them but I don't know what will fit. If anyone out there has any experience with this I would greatly appreciate some input. If I can't get any info I'll let you all know what I find out by winging it! :lol:
