Trying to get some more done on the Indy of late and want to pick your collective brains about a few things please

Is this an idle adjuster? or is my guess wrong?


Do I need whatever this is?


And finaly for now. What are these pipes for? (circled in red) are they something to do with coolant for the carbs, and do I need the in the indy?


Thanks
Ben

the first one is a idle adjuster from the looks of it.

the other two, i am not certain on

stuart

The idle adjuster is a simple stop to prevent the throttle butterflies closing completely. It is handy for setting the revs to 2500 RPM for emissions testing so you can leave the throttle pedal alone.

I can't see the pictures (work internet blocks some hosting sites) but there is a brass pipe through the carbs. You pass warm coolant through it and it stops carb icing in cold weather. I only found it to be a problem in freezing fog and a trickle of warm coolant to my header tank sorted it.

im pretty sure the one you circled on the bottom left is the fuel inlet

in the top pic il looks like u have connected the fuel line from the tank to a t piece which go's to 2 pipes to the top of the carbs
these are breathers

idler
the second picture is like filter/regulator for the emmisions system which u dont need to run so it can go
the third pic
bottom left if fuel inlet and top right is for coolent i dont run it on the indy as i dont have any problems
