BEAUTIFUL engine kerker. gotta love the flatheads.
I must have missed the back-story, but I always hate to hear of failed attempts in setting up ITB systems. having been down that road myself, and won, I know it ain't always easy. the rewards can be great also however.
But in the end, it's better to have a great running engine than just a great looking engine.
Can you direct me to a pic of your flatty with the itbs still on it?

Thanks,
Russ
