I've got the pnp with an evo 46nt. I can't get full throttle anymore. I have re gasket-ed the engine, took the baffle out and bought new glow's. But no luck. Today I replaced the fuel tank and all the lines but still have the same problem. I also flushed out the valves. Any ideas?

I did notice that when i go to full throttle the gas runs back out of the line back and into the tank.
