Tick over revs?

Hi Bongo Folk.
Does anyone have any idea at what the Bongo idling speed speed should be at tick over once the engine has warmed up ? Mine ticks over about 1050 which seems a little high.Daddycain,Tribal Elders,Miss Fixit ?
Bertha ( the Bongo ) is now repaired and looking her old self again.However she failed her mot the other day.Fog light and exhaust emissions.Fog light sorted.There was not even a feed to the switch.Changed fuel filter and got some injector cleaner.Checked air filter and was it was ok.Will do the Italian routine ( Fact Sheets ) and put her in again Monday
Was suprised about emisssions as she runs so sweet.Starts no problem and not a sign of smoke.I was just about to start trying the veg oil route as well as I had read that it cleans out the system. One thing I did find that helped while changing the fuel filter. Fact sheets to the rescue again!!!
I dont think mine had ever been changed.Khaki in colour and one hell of a job to remove.

Found that by undoing the main body ( two bolts ) you can then get a short piece of batten 12" to 15". Place it under the filter after lifting filter free from the housing and you can rest the filter on it at about 45 degrees.It was the only way I could get a filter removal wrench to be workable and believe me it helped.This was working from above after removing the air filter top and first hose run,that bit was simplicity itself.
Hope this helps someone else who may hit on the same problem.
Thanks once more to all the knowledgable folk on this site.You really are the tops.

Mine ticks over at approx 750-800 rpm - 1050 is very high.
Unfortunately I have no idea how you adjust the idle speed, but hopefully someone can help.

Thanks Broro.Thanks Franco.
750-800 rpms would seem to be about what I would expect for an idling speed. Am pretty sure I was looking at the adjuster whilst changing the fuel filter this aft.Pretty much straight in front of filter few inches higher and a bit to the right.It can only be for altering the revs.I will give it a go tomorrow.
Anyone know better please let me know.Dont like to mess with something thats not really broken.
Thanks again.

Think the book says 700rpm mines at about 750
the tick over adjuster seems to be the threaded
micro switch thing with the wires going to it but
not at all certain, cant see anything else.
One thing is the throttle arm against the stop
or is the fast idle arm holding it open if so
it may be a temp sender or vacuum valve thing.
