KartDen

Sunday practice is toast if I mess this up in the garage tonight. Putting a new Inferno Flame on the cadet and it just wont take, feels like the kart never really launches. Before I start chasing springs, is the first move just confirming the hub is locked to the crank? Key seated, taper clean, nut actually tight? I dont want to burn an evening on shoe direction if its spinning on the shaft the whole time. What do you all check first when a brand new one wont grab?
