I know this is probably asking for a lot but I am currently in the process of building my tool box for the paddock. I run a ka100 and an OTK Chassis and was wondering if anyone knew the most common hardware sizes (i.e. nuts, bolts, screws, washers…) for me to keep a lot of in my paddock tool cart. Or just any other general advice of things to ALWAYS have on hand. (I know there are threads for kart tools but I couldn’t find anything on specifically ka100 and otk related threads)
Hardware. Just lots of random crap that I unfortunately can’t be more specific
KA. Diaphragm kits. Spark plugs. Clutch driver. Reed cage gaskets. Throttle return springs. Exhaust springs. Spare egt probe.
Otk. Grub screws. Front seat mounts. Steering wheel hub bolts. Front pill adjuster tool. Neutral pills.
That’s the quick off the top of the head list.

Bring a steering shaft and a couple of tie-rods.
