bad timing?
i just tried to start my car up for the first time. no fire, i check for spark at the wire and im good. now it starts to spit gas right back out of the carberater. timing?
also wen i turned my distributer retarded (lol) it lit up a huge flame in my carb. so then we took a break and roasted some marshmellows. but we did the same thing again and another flame.
i was thinking my motor is 180 degrees off but wen i took my dis cap off the rotor was at #1 cylinder.
can any1 help me ??

Your rotor may have been at #1, but where was the #1 piston in relation to TDC of the compression stroke? it does sound like the distributor is 180° off.
I would just start over with the timing setup. Pull the #1 plug and put your finger or the butt end of a large screwdriver. **UNPLUG THE POWER CABLE TO THE DISTRIBUTOR** (i cannot stress enough that this be done). Have a friend bump the starter over until you start feeling pressure build behind your finger as if its trying to get pushed off. Then swing the timing mark around to TDC. You are now on TDC of the compression stroke. Now rotate the distributor around so that the rotor points to the terminal on the cap that you have designated as #1. It really doesnt matter which terminal is used for #1 as long as the rotor and cap terminal reflect upon eachother and the firing order is followed respectivly. Once you have done all this, tighten down the distributor clamp. Dont tighten it 100%. Leave it loose enough so that you can rotate it by hand, but tight enough that the pressure of the cam cannot wobble it around or anything like that. Plug the distributor back up and fire it up. You may have to twist the distributor a bit.
See if it catches after doing all that.

try turning the rotor 180°. i had exactly the same problem like you. huge flames out of the tbi etc.
after i turned the rotor, it has started right up

Just because it is at TDC, does not mean it is at TDC of the compression stroke. There are 2 TDC's per combustion cycyle. a compression and an exhaust. the #6 shares the same up down movement on the same pattern. When #1 is TDC exhaust, #6 is TDC compression. And vice versa. If you installed the cam sprockets dot to dot, your setup is 180° off.
