My Onan QG 3600 LP generator is running poorly, thus video is to show a friend the problem.

****update****

Mechanically I never found anything wrong with the genset. What I determined is it’s just cold blooded, my issue gets worse when it’s colder out, BUT if I just let it run for a few minutes it warms up and runs perfectly. No magic fix, just let it warm up. Now that summer is here it starts and runs perfect right out if the gate.
