I don' know for sure I didn't install them. I did tighten them up a bit because there was a gap between the rubber spacer/gasket and the manifold. I couldn't fit a torque wrench in there to make sure how tight they were.

You can see the crack or hole next to the right bolt in the first pic and top right bolt on the second two pics.
I have a 1974 620 with dual DCOE 40 webers. I was tightening one to the manifold on the bottom nut and my wrench slipped and put a pin hole chip in the bottom of the carb. Now I have gas leaking out. I was wondering if I could JB weld it for a quick fix, if I can tac it with an aluminum welder, or am I just screwed all together?
I have a 1974 620 with an L20 B. Every time I shift into 2nd it pops out of gear especially when I down shift. Do I need to rebuild my tranny or should I just find a new one?
