Now that the temperature has dropped, I'm finding it difficult to start my 360 in the morning.
I've bridged the thick white wire on the thermal time switch to earth (hopefully the right wire) in an effort to ground it, but it doesn't seem to have helped.
I'll take the cold start injector off tonight and see if it does anything.

Otherwise, I've cleaned out the air idle control valve and the throttle body.
I've ordered fuel filters too.

Anyone have any other things I could check?

My first thought would be cold start injector or a diety/blocked fuel injector.
