yep, am upto 6 out on top now :/ still runs hot as a mofo
spit on the crankcase it'll boil till dry.
Bottom is 3 1/2 out, havent changed it.
Changed glow plugs to a longer plug, and then to 0S #8 :/ Longer plug runs the motor better lean, great punch, and top end speed, is just hot as hell. :/ i have no temp gauge, but the water will boil like its hit a hot plate of your stove :/ the force12 and OS never got this hot, only once, and that one has a new sleeve/piston due to that :0
Any plug you'd recommend ? I dont have a manual, and novarossi.com aint been up in 3 weeks for me
