Check my pics in the other monster truck section, I'm on the fourth tank and its starting to get impressive, the pull start has held up great and it has yet to stall, its running about 205-210 for break-in w/ 20% byrons and #8 med plug will go to 30% on the 6th or 7th tank w/ a #9 plug, I've only went two 1/8 turns so far and when I blip the throttle it will spin the tires w/ my jumbos and aluminum rims!I'll keep ya posted!
