Hey guys just swapping my old drover carby over to a secondhand one... found this lil pipe which the drover one doesnt have (see pics below)

Any ideas what it is for what I should connect it to?

[peeeete]

two pipes on drover one... this is on the engine side of the carb...

[DMAC]

The two on one side goes to the dizzy and charcoal canister. The other side goes to a solenoid towards the front of the motor.
I've got pics I'll try and load heaps easier to follow. Won't be long.

Two going to #19 to dizzy and #27 to canister


The other one #18 going forwards along rocker cover.



The forward one goes here below the thermosat .



Hope this helps.

[peeeete]

yeah it does cheers DMAC! my only prob now is my old carby only had the one going back to the dizzy... so these carbs probably arent compatable?

Just block the second one off.

I assume (i may be wrong) your drover doesnt have a carbon canister and vents the fuel tank breather to atmosphere.

The second plug which runs to the carbon canister is solely for emission purposes.

[peeeete]

sweet nope still got the canister but its connected to something else i forget where...

but does the car behave any differantly when you switch the headlights on?

Interestingly I have this happening with a G16A Vitara - just had the carby rebuilt and noticed it last night that when the headlights are on the idle is all over the place. What turned out to be the fix?

There is a small vacuum pot at the front of the carby. When the headlights or other electrical load is applied vacuum is applied to this pot. This pulls the idle up throttle stop in, raising the idle. Get a mate to switch the headlights on as its running. Watch at the front of the carby and you should see the little lever pull in. If it idles really high, adjust the stop down and vice versa. ~800rpm is correct for electrical load on, and ~700rpm for no load. (from memory, im sure if im wrong someone will point it out).

[Rockhopper]

check to see the choke flap opens up when the car reaches operating temp

[Jord]

when u say open do u mean wide open, or do u mean just a gap?

[suzibob]

When engine is at normal op temp, the choke should be wide open (straight up and down)

[Jord]

think that may be what the issue is as it is only got about 4mm gap. will have to check it out tomorow

[Jord]

Oh yeah sorry guys, If i need to get it to open up more, whats the best way to adjust it.


thanks again
Jordan
