RE: xyz cdi
Michael did you finally use and understand the piston stop method? If you did can you now see why using a dowl to try and feel the piston dead spot would not work real accurate. Its not that hard to make a piston stop. Its so simple once you understand it.
Sounds like you got it right this time if your engine is running that good. Isnt it nice to know your dead on where it should be and you dont have to guess and hand tune it?
Like I say this subject has been discussed to death on here. I just dont understand why it is so hard to understand when the process is so simple.
I think if I can afford to get another ignition box and i can find someone to video and edit me, I will make a video of this process and place it on youtube. It really seems there needs to be an instructional video of this.
