Whats wrong with my 1.3 carby?

[Meteor]

After a trip to stockton beach on about the hottest day of the year the other day the sierra has been has been idling almost 1000rpm higher than usual (up to 2700 at the lights ). The temp has been sitting around 2 needle widths higher as well. Raditator is near new, idle is not related to having lights on etc. so nothing in the search....

sand in the carbi, take it off and blow everything out.

no sand, just found the screw to adjust the idle has half it's thread missing... bugger

sounds like auto choke may be sticking on....often caused by too low water level, or blockage in pipes that feed the auto choke.
running hotter suggests a water flow issue, which can affect auto choke.

well my car uses like no water not sure if thats a good or bad thing...

did a 800km drive once and the water barely went down at all

so could it be a blockage? and how could i find out

cheers

The pipes running in and out of the auto choke should be warm to hot when car has reached running temp.
If one pipe is cold, it is not flowing.
Pull one end of and blow the crud out usually works.
You can also see the mechanism slowly move up as car warms.
worth a look into.

check your choke, too, water can get air locks or crud in them, causing ckhoke to stay on, which in turn keeps the idle high, cos it thinks it cold

my nuggets have often been unwise, judging by past women

Officially the wax plug that moves the auto choke has stopped working, will know if it's a water flow issue tomorrow. Couldn't go on driving it with the idle getting up around 3,500, brakes would be f$cked in a week.... Having the thing start up like an old radial engine did sound kinda cool though.
