If the timing was off, you should have running issues at all engine speeds. I'm not too versed on the GY6 timing marks, but honda designed them to be pretty easy to read and align. If you are unsure, it never hurts to make 110% sure.

In a previous post you stated it ran well with a 126 main and you changed to a 128 when you opened the carb to change the pilot. I would revert back to that as a starting point. Although it is cold, it should be able to run without the enrichment valve after it runs ~5min or so, even in subfreezing temps. If it's open even a little, it will be rich and run like poop.
