Rotates but not starting - The 1947 - Present Chevrolet & GMC Truck Message Board Network

my 85 w/ a 305 rotates but does not start up. I took it to chevy and they said I needed a new carb. They wanted $50 installed so I told them I could get it cheaper somewhere else. So I had two carbs rebuilt and I still have the same problem. I decided to check the timing belt and it was about to come of the crank gear. I replaced the timing set and went by the haynes manual for getting tdc. Turn crankshaft until the balancer line is at 0. Look at the rotor and make sure it is pointing to plug #1. Everything looked in time to me. Well I get everything done and all the accessories back on and I tried to crank it up and I still have the same problem. It shoots fire back up through the carb.

It has to be some kind of timing issue but where should I go from here?
