If covering the head alone won't get it to heat up, you have to lean the needles down. Those OEM settings are only set to get the engine started. It's often overlooked in manuals so new guys don't always get the right information and their engine's life suffers because of it usually.
I've always had to lean the needles on my engines to get them hot enough when new.
