Mitsubishi FGC25K 0R FG25K:
Slow idle at startup then surges up to normal idle

Hi everyone, I am hoping that someone may be able to help me out on a problem with my truck.
I have a Mitsubishi FGC25K with a FG63 engine on LP.
When I came into this truck it had a blown head gasket. I did the repair on that, and now have another issue that arose after I put it all back together.
When I start the engine it idles very slowly, almost as if it is going to die out, then surges up in RPM, then drops off to its normal idle. I took a video of the problem so that there is an audio element to my question.
Any ideas where to start with this? The engine did not do this until I did the head gasket repair.
Thank you in advance for any help.
