Re: no rough idle

You are correct that the cold start valve is only on during cranking 
of a cold engine (below 95 degrees). What I meant to say without 
getting too technical is that on an initial cold start even after you 
stop cranking the engine, until the raw fuel from the cold start valve 
is vaporized and consumed the idle motor cannot take full contol of 
the idle. So even though it is true that the cold start valve is 
closed as soon as you release the starter the effects take a moment to 
wear off during which the idle will be "unstable". I hope this clears 
up my description for you.
