hi i own a escort series 2 ive recently rebuilt the engine and it was running fine but for some reason now it wont idle it just stalls its fine wen its runnig, so long as u dont let the revs drop, ive tryed the idle valve and wen its adjusted its fine also to with the throttle cable, until you turn it off then it just stalls again. can anyone help cheers.

 

I would check CO and for air leaks.
