If your track’s fuel requirement is non-oxygenated fuel, then street gas with ethanol will not pass it and you won’t be able to run it. You could of course get the rest of your class on board with getting the lead out of karting and agree to all run 93 E10 to give an identical reading in tech, or change the rule.
I start and idle the engine at the end of the day, disconnect the fuel line from the carburetor, and run it dry, choking the intake and shutting off the ignition when it goes lean and revs up. The only ethanol-related problem I’ve had occurred when I borrowed someone else’s kart who hadn’t done that, and found the jets clogged and the floats fuzzy with green residue. Tillotson gaskets & diaphragms last as long as a piston for me.
My TaGs have been fine on E10 93 - actually, they’ve been a lot less trouble than the engines I ran on racing fuel.
