1995 Honda Civic No go

I have a 1995 Honda civic with a stock D15B7 SOHC. I was driving on the highway one day and I lost all motor response. I later found out it was my timing belt that broke! Me and my friend which are both ASE certified decided to do a rebuild from scratch, replaced all gaskets, spark plugs, spark plug wires, cracked hoses, radiator cap, pcv valve, fuel filter, fuel pump, timing belt, alternator, battery terminals, battery, ground wires, cam gear, and all other necessary parts and some unecessary parts like fuel regulator and what not. I put every thing back together by the books checked twice by me and my friend. It started up just fine on the second attempt. This was back in april of '08 I left it sit for 6 mounths and went to start it up and all it does now is back fire and blow black smoke when I try to start it up the timing is off I know this for a fact I am getting spark and fuel and reset the timing again but still nothing please help need car one road again only car
