I have one of those IR thermometers with the laser pointer, but I'm not sure where I should be measuring engine temp. Obviously it's hottest around the exhaust port, but I'm not sure that's where I should measure temp.

On a related note. I have a Raptor 30 with a TT36 in it. The engine seems to consistently lean out, overheat and lose RPMs after about a half tank. I've been frustrated trying to get just the right idle and high end mixture. I'm guessing it has something to do with lack of muffler pressure to the tank, but I'm not sure. I have one of the TT shiny aluminum pipes.

If I fly around for a while (5-7 minutes) and land with a half tank and go to idle for over 15 seconds, if I try to spool back up it dies abruptly at about half throttle. Right after quitting, the exhaust port / crank case temp measured about 210 - 220. This seems hot, but if I richen the low end it won't idle.
