I'll grab frame and engine numbers sometime when I feel like getting grubby.
Not sure if the fuel pump is oe, but it's mechanical and labled kyosan or something similar.
I'll try to get a plug on that open tube on the carb... I actually thought it had a plug on it until you mentioned it.
How can you tell the year of the carb? Is it possible they were using these carbs in 77 if we both have them or is it a common replacement?
After reading more about registering in different counties, I think I'm going to try to pass the visual with what I have, an air rail and smog pump (assuming I can find both) and then see if I can tune it to pass. Trying to find all the little bits and pieces seems daunting and probably not necessary... Am I on the right track?
