It's got to be a bigger thank than stock. I don't know if it has over overheated, but it gets hot. It never boils, but it seems to get very warm. I should take the pyrometer and get a temp when it hisses out of the vent.
How hot is the cylinder getting? Mine will get warm to the touch but not hot. Filter is about the same, maybe a little warmer. The tank is just warm. But like I said I usually work it in October or November. I've never run it when it's above 60 outside for more than 20 minutes or so.
