3.3 break in issues

[SteelCityNitro]

Ok, so I just rebuilt a 3.3.. it's the first rebuild on this one. I checked everything out and replaced what needed to be replaced. I got through the first tank just fine. Tank two, however, the engine kept stalling out on me. I've never run into this during break in. Any suggestions ?

If it's loadin' up you may have to lean it a tad.
