Hook it up to the fuel return line back to the tank.

2. Is it okay for these two ports to be capped off?

You only need the vacuum line to the distributor - all other lines are superfluous.

3. This tree of vacuum ports, can it be removed and a bolt put it block this off?

Yep, unscrew it and install a grub screw or a bung of some sort.

4. This is the other fuel line. I imagine one is a return line but what is the other? and can they both be capped?

On the Mikuni carb there is a secondary fuel line that goes to the accelerator pump on the side of the carb and another line that goes back out to the fuel return. This secondary line from the fuel pump is connected directly to the fuel return.

5. This line I capped off because I seen that done on another thread somewhere and it goes to a manifold that has something to do with cooling

Bingo. If you want to make your manifold dedicated to the Weber install you can remove the coolant barb on the manifold and use a single barb, then thread the coolant port with an M6 tap and seal a grub screw into the port to block it off.

6. I have not seen on any other thread what is supposed to go to this port on the carb and the instructions make no mention of it....wth!

That is the fuel bowl vent - hook this up to the vapour cannister that feeds back to the tank.

The factory fuel pump will over pressurise the Weber carb and cause flooding and generally make the engine run poorly. Adding a regulator to the mechanical pump will cause the pump to die prematurely so you will need to install a low pressure high flow pump. And if the Weber carb you have bought doesn't have the Weber logo cast into the body of the carb or on the external pump covers, it's a fake. Sorry to see yet another victim. The problem with the 'licensed' copies are from the way they are manufactured. The internal fuel metering galleries aren't jetted and can't be changed due to them being integrally milled into the alloy casting. Doesn't matter what you do to the main jets, it will either run lean or rich...
