I need all you nitrous guys...

No I havent checked the plate with the carb off, Ill look into that. I do have a full msd ignition, with a retard control, I take 4* out when the nitrous is activated. I have a electric fuel pump, with a regulator set at 6.5 psi. Ive ordered a bottle heater, and a purge kit. So, Ill install that and check the other ideas you suggested while doing so, and hopefully well find a fix to this problem. Any other suggestions are welcome, and appreciated! Thanks for all the help.
