Predator 212cc wheels spiningredients as soon as I start engine

#1
Can't figure out why my tav2 engages as soon as I start go kart I took the linkage off of throttle but the wheels will spin on the lowest possible setting also fouling plugs like crazy and when I try to give it more throttle it boggs down and dies it has also backfired a couple times any ides???
