sounds like the block is flooded usually a sign of too much fuel or not enough compression or the timing being off it has been apart recently.

best thing to do with your sled is:
Check compression (anything over 100psi is good)
Rebuild the carb (I'm guessing it is a Tillotson (sp?))
New plugs and caps
New points and condenser (and time to spec)
fresh fuel

your issues are more then likely timing is off, and a gummed up carb, but always check compression first, as this can cause your issues as well
