Thanks all.

 

The link below must refer to a different model and I can't find the air
valve thingy.
Just one thing on this, and that is when I start up and the tick over is at
1500 rpm then
if I rev it up high it then drops back to about 1000 rpm the slowly falls to
850rpm.
If the air valve was dirty, wouldn't it be a bit more constant?
What bit tells the engine management the air intake temperature?

Cheers.

 

well what engine have you got then?
there are other sites to other engines
