westach temp sensor is best, made for small aircraft and reeds up to 600+F and has sparkplug sender reader
wow, i think the next size is a 52, run a 50 now. guess can try it again. had it in for a few hunderd miles, seemed pretty rich and never seemed to run cooler but its not a big job to try it again.
