Track tool box

FIRE EXTINGUISHER! (you never know), duct tape, air tank, extra fuel line (2ft. should do it), First-aid kit, flashlight, magnifying glass/flashlight if you don't have one (gotta at least read the plugs to adjust jetting!), zip ties, a friend to take pics of launch & burn-out (video is better), any spare ignition parts you may have, a battery recharger, spare fanbelt.
These are minimums, IMO. I'll be running around tomorrow, if I see ya working on the car I'll stop by & say "HI".........Good luck!
