    Need help with start up issues

    Here is my mod list, Its burning rich when it starts. Fouled the plugs after only 10mins of running. It's on stage 1 Eurodyne. I have no 02 sensor's in it ( dont know if that's hurting or not) Now it just cranks with no signs of starting. No misfire codes. When I crank I definitely smell gas. Any ideas?

    Just after the build, I put the front o2 sensor back in.
