Timing is out on a new motor.

I am wondering if my problem is just that I flooded/fouled/burned up a set of plugs and all I have to do is install a new set of plugs.  Is this possible.  I will try this next but I would hate to put in a new set of plugs and foul them up as well at a cost of about $4 ea.  Also, the spark plugs have writing on them saying "AC Delco" and "4" underneath that.  How do I find out what plug this is or will the parts store know if I bring them the plug.

What kind of fuel pump are you using? A Holley needle & seat can't take much over 7 psi before it gets overwhelmed and starts to flood. Also, how did you set the floats? All the lip service about taking out the sight plugs in the bowls and adjusting the float up until gas begins to dribble out is absolute b-s. The float is always too high that way. You take the bowl off, invert it, and set the top of the float just even or a little below the top bowl screw holes. I feel for you, man--this has to be driving you nuts! Good luck!
