Here's a puzzle. I had to remove the carbs on my 79 to put starter valves back in correct position (some PO had inverted left and right). On reassembly, as you see on the photo the r.h. air inlet pipe will not align with the air filter, it's way off centre. Funny thing: before I took the carbs off it all lined up and fit perfect. Now I can't get it to line up no matter how much I jiggle it all around. What's going on?
