wholdguy 73 #1 Posted September 27, 2015 The other day rain was in the forecast so I had to hurry up and get the yard mowed. I spent just under 2 hours to finish up and then I thought of a project I have always wanted to do. I used the Charger 12 with the Tecumseh HH120 engine.I have this Fluke IR Temperature measuring tool. It's good for finding hot bearings, brakes etc. So I used it to measure the exhaust pipe temp, just in front of the muffler, with the engine at idle.The temperature measured 565 deg F, and this was just as I finished mowing. I thought this was interesting to know. Someday I should meaure the head temperature at the cooling air exhaust side.G. 2 Share this post Link to post Share on other sites

clip 185 #3 Posted September 27, 2015 I definitely wouldn't want to touch it. You should adjust the mixture and see how much the exhaust temps vary. Share this post Link to post Share on other sites
bmsgaffer 2,053 #4 Posted September 28, 2015 I temp'ed my Onan just the other day as I was trying to cure my exhaust paint and wanted to make sure it hit the cure temp...I read 650 within 10 minutes with only an idle hydro pump for load... 1 Share this post Link to post Share on other sites
