hmm, but I haven't broken it in yet. It wouldn't be good for the engine if I floor it. The manual for the truck actuallly says, that messing with the needles when weels are off the ground will most likely damage the engine.

It seems to me, that it's either too rich or too lean. It is stalling because it either get's not enought air or fuel. I don't think, that I should be revving up the engine on the first tank. I think maximum should be only 25%. I have heard, that some let it drive with the idle set higher and break in like this. Don't know if it is wise though.
