    I changed my intake and Carb. over to a 4bbl, and now the car wont start I bought a new battery and all it dose is back fires. I think the timing is off but how do I fix it if the car wont start, it trys to trun over just back fires.

    If you can help thanks

    first off is the fireing order right on the distributor?
    did you put the distributor back in with the rotor pointing in the same direction that it was before you pulled it out?
    is the housing of the distributor in the same or close to the same location as it was before you pulled it out?
    does fuel come out of the squirters in top of the carb when you open the throttle blades?
    answer these questions and we can get your car to start.

    the housing of the distributor is the same way it was before I pulled it out but the router isnt I dont think, the fireing order is right, as for fuel coming out of the squirters in top of the carb I am not seeing any when the throttle blades are open.

    You need to get the motor to TDC. Then get the rotor pointed toward the #1 plug wire. Then try to start it. Sounds like the timing is off if it is backfiring.:)

    pull the #1 spark plug out. get a friend. put his or hers finger in the #1 spark plug hole. put a braker bar or large rachet on the center bolt on the balancer now rotate the motor clockwise when your facing it. when your friend feels a good amount of air push past there finger you are on the compression stroke. now pay attention the the timeing marks on the balancer. when 0 reaches the pointer stop rotateing the motor. you should now be on #1 tdc. now check where the dist. rotor is pointing. it should be point right at the #1 post on the dist cap. at this point you should be able to get it running if this was your problem.

    as for fuel you need to be looking over the top of the carb while you move the throttle lever and have the choke flap open. if there is fuel in the carb you should see two streams of fuel shoot down the carb. if that doesnt happen your not geting fuel into the carb.

    Dont crank it for more than 15 seconds at a time.Give starter and solinoid a few minutes to cool down after a few attempts.Dont pump the heck out of the throttle either while cranking.Give two good pumps and try it.If your close it should burp/fart or fire up.If it still back fires out the carb your timing is still off.Good luck
    After repeated attempts to start it you may have gas soaked the plugs by now.Might not be a bad idea to pull em and dry em out if its still being a pain to get running.

    You might be 180 out and trying to fire on the compression stroke. Rotate the motor arount to the next top dead center(TDC) on number 1 cylinder and you will see that the rotor is backwards to what it was. All you have to do is pull the distributor out turn the rotor so it is facing TDC and it sould fire if that is the case.

    dont try rotateing the dist 180. your really close try turning the dist a little bit one way and try again. if it gets beter the go further. if it gets worse go the other way. your close, keep at it.
