Increased idle speed

[topchef]

Hello all, finally done the viscous fan repair....blowing a gale in the bay now lol. But...idle speed has now increased to 1100 rpm, from 750/800! Even after a good run it still has higher revs, the idle up switch now runs at nearly 2000 rpm, up from 1700 or so. Any clues as to what has happened, should I be concerned, will it increase fuel consumption whilst running ( ie not idling). Or should I just get used to it? Did the repair after a great deal of searching/reading on the forum so, many thanks to all who've done it and posted info, particularly to those who made a few pics of procedure...invaluable!! Cheers in advance....

It won't increase running fuel consumption.
Nae idea why it's went up though.

Have you left a ratchet laying across the throttle cable

Belt's tensioned properly?

Belts were not touched during 'refurb" so no change to them. Wondering whether there is a temp sensor ? that acts like a choke until a pre-set temp is reached and then lowers revs. Just fishing really and hope there is a definitive answer.....

Have you knocked the 'idle up' button ? Not sure if fitted on 2nd gen but it is on 3rd gen and have left mine on by mistake before and had the same problem with high revs until I realised what had happened.

Not idle up, if I use that, it runs even higher as I said. However, idle up only works when not in gear. I'll keep searching and see if something similar has happened to someone else and/or what the remedy could be. Tx anyway

Is the throttle cable completely closed on the inlet manifold ? The bit the cable attatches to should be resting on a stop screw.
