Even though the tank etc. is new, how old is the fuel? I’ve got cars that don’t go a lot of miles, and I’m seeing clean, good looking fuel become a problem is as little as 4 months. Especially filled in the fall and started in the spring. Much more vapor lock problems than the old days. I don’t know how they blend winter/summer now, but it seems to me the Reid vapor pressure wasn’t as big a difference in the past. I blame it on the ethanol, but I’ve got no evidence. Drain it, fresh fuel, problem goes away. Both the cars and small engines, I just went thru this on my back up generator after a winter with no long power outage.
