Club car 2001 ds gas powdered will not start

I have replaced coil, carburetor, fuel pump, and filters. The cat will turn over but will not start. I have squirted gas into the intake and get fire out of exhaust port but still not start. I have disconnected the ground on the rpm limiter and same thing. I have checked all the limit switches and all are working. I have fuel flow at the carburetor. I am out of ideas can anyone help with an idea. Ricky
