Can a pullstarter kill / keep engine from starting?

So finally got some time. Couldn't even get it to fire. Its about 72° here. Guy at hobby shop said not to
run it when its over 80. The glow plug went bad before this started. Could I have the wrong glow plug? Sorry I forgot to mention it slipped my mind...

You can actually run it in any weather, just remember that colder weather will cause faster wear without pre-heating.

I used to run when it was in the high 90s in the Rio Grande Valley. You just need to watch your engine temps and make sure that you have a good smoke trail.
