<< I also discovered that I had to remove the carb, intake manifold and stainless steel header. The header is one piece and you can't separate it at the flange like the cast-iron manifold to remove the starter. >>
When I installed a header a few years back, I took the advice of fellow Alpiner Jim Leach and had the muffler shop install a flange at the end of the collector. Made a lot of repair projects since then much more tolerable.
