Fresh Rebuild; not starting

You say TDC. Do you have it TDC on #1 cylinder, compression stroke? To verify, pull #1 plug, insert finger in hole, bump it over until you feel pressure trying to push your finger out. Then double check for rotor position, make sure it's pointing to #1 on the cap. You might also want to make sure the rotor is turning when you bump it over as well. Let us know what you find.
