Is this a college course or maybe garage apprenticship??

4 is correct

1 is also after a certain point.
So is 2 on cold start, as soot accumulates on the plug more easily.

Im not getting baited in to an argument over something you may have misread or understood. Maybe you should read through the post again?
I dont think a simple question should warrant a hostile imput as yours, considering the question was not even for you! This is a friendly forum and there is genuin interest in what others are trying to acheive.

[kninio]

I think 4 is the answer they're looking for.

Kninio, I think Moggies was just interested in what kind of course you were studying, I really don't think his comment was in any way sarcastic.
