RE: BME 50 gas/oil mixture
I used a laser temp guage and I took a reading off the lower cooling fins, top of engine, and were the spark plug goes into the head. The highest reading was 245 were the plug goes into the head and on the lower cooling fins. Middle point of the engine seemed to be at 198 to 200. I think these temps should be good but then again I am not very knowledgable with gas engines.
