Yea, I'm thinkin the gauge is accurate.cause after It runs out of gas....I refuel and am able to hold my finger over the pipe(to prime it) and its not hot enuf to burn. I will tho test the temp while it is running. maybe I'm waitin too long to take the temps. Like I said out here in the high desert(lake tahoe area) It gets quite breezy....maybe its coolin off before I take the temp....Thanks again for your help
