A restart in the air would be completely different, because everything
would immediately cool down, especially the injection and induction
system. It would be like a cold air start with a warm block, perfect
conditions.
I don't have a problem of the starter not turning the engine fast
enough. Just can't get the priming/mixture settings correct..

One thing I do that helps a lot is to get things as cool as possible by planning a low power decent, straight in if possible, and shut down asap after landing. I am concerned that I would have the same problem trying to re-start in the air. One of these days I plan to run a small cooling air line from the plenum to the starter.
