[Nobbc] timing and tuning

[rlmossholder at comcast.net]

Hello,
  I wish I could have been on the ride this last weekend, sounds like you all had a great time. Nice photos too!
  I have a question about timing and tuning for my Spitfire. I have a Weber DGV carb  and I just installed a 4-to-1 header. What type of adjustments to the timing and carb should I make? I've never turned a screw on a Weber before, and am a little nervous about changing any settings. Any advice would be greatly appreciated.
Thanks,
Rich M
