87 l series fuel few questions

[su87bi]

Just wanting to know a few things about me subi,

 

#1

 

on the air cleaner , on pass side there is two hoses that go out of it, one is

conected to valve cover and the other just sits there ? is that correct ?

 

#2

 

the screw on the front of carby on front of car , is that fuel mixture screw ?

not sure what it is

 

#3

 

when driving there isnt alot of pick up and go, but in 4th do 80kms an hour you feel a jolt then the car car kicks in and has alot of power and takes off. any ideas why it does that ?

 

also the temp gauge goes up for a while then goes down and some days it dont move from half at all, can that be thermostat or mixture prob ? any ideas ?

 

thanks again
