How long does your Wait To Start light stay on?

This time of the year cold starts produce lots of smoke.

You need to plug it in for at lest 2 hours every morning.

If you smell fuel at idle you probably need to change your return lines. Atleast that is what mine needed. Starts much better with alot less smoke.

Cold engines will smoke until the chambers come up to temp. If you plug it in the chambers start at a warmer temp so it will not smoke as much.
