Haha, busted! Total "can't see the forest for the trees" moment right there, Nobbe!
I was so busy checking the small details that I completely blew past the fact that cylinders 1 and 2 are running strictly on fresh air and good vibes!
Looking at it now, it's pretty hard to miss that lonely crossbar reaching out over the empty cylinder tin with no intake manifold or carb to bolt up to. Cylinders 3 and 4 are over there looking ready for race day with that gorgeous dual carb and velocity stacks, while 1 and 2 are left hanging.
What carbs are you running on here—Weber IDFs or Dellorto DRLAs? 40s or 44s?
Once you get that mate bolted down, sync the linkages, and hook up that 123ignition, that’s going to be a seriously sweet running setup. What are the rest of the specs on #0013? Displacement, cam, and heads?
