The snow around the trailer I had this tarped on was finally high enough to drag it off and try it out for the first time! After resealing the motor this Summer, I had never even moved it under it's own power until tonight. It actually gets around pretty quick with this little JLO, but seems to run kind of hot...A-7 is supposed to be the correct NGK plug, but I think I will pick up an A-8 and see if it runs a bit cooler...
