Hello all, Just a quick brain pick. Do both air inlets on the carb mount boots both need to be connected to the petcock or should one be capped off? I have an sohc 1980 se us custom which I'm still trying to get running. At the moment it still has both inlets connected but after perusing the...

I'm going to rebuild my petcock with a new rebuild kit and was wondering if I need to use any gasket seal on each diaphragm? I also wanted to check that I'm right in assuming the plastic square washer bit goes between each diaphragm? Any advice greatly received!:shrug:
