Hi Mowerfreak
80:1 is indeed extraordinary.
I was surprised with my 125 edger (not low comp, but a very open area around the motor), how cool the motor is after a reasonable run (1/2 throttle max) - I could literally hold the cylinder head 5-10 minutes after turning it off. I have always run it on 25:1 - as the sticker on the tank says. I thought it was strange it said (effectively) 30:1, once I worked out there was 20 fl oz in a UK pint (not 16) - making 1/3 pint in 1 UK gal = 25:1.
Next time I start it, I will use a infrared thermometer and compare temps to a fully cowled powertorque. Might be interesting.
I would be more happy with 50:1 as well - what oil do you use? I'm currently running Penrite semi synthetic 2 stroke oil - but I will probably go full synthetic next time i need to get oil.
Regards
Tyler
