30 is getting down there in temp. I would use better lube as suggested...or even add some oil to the lube you have. That will thin it out more. You may even want to redo your reg like that.
Check all the stuff mentioned above. Last but not least.....raise your dwell. That's pretty much standard practice for spoolers once the temperature starts to drop. Ideally I suggest you climatize your gun to the temperature you'll be playing in before you set the dwell. What works good indoors at room temperature isn't going to work outdoors once the gun chills.
