    350 not starting

     



    i just put in a rebuilt 350 in a truck that i am redoing and primed the engine and got everything timed and adjusted right, but when trying to start engine it starts to crank faster like it wants to start but then dies out and then shots flame out of carb. in my past history with this it was timing but i have triple checked the timing and its dead on and i checked spark its getting good spark. could something in the valve train be bad. thanks

    Did you adjust the valves? If everything is new, the valves should be 1/2 - 3/4 turn from zero lash (I'm assuming you have hydraulic lifters). If you have them too tight you'll get a fast crank and fire out the carb.

    i havent checked the valves yet but the motor was rebuilt and ran 6 times and the guy recked the car and i bought the motor from the guy. also it wont flash out the carb unless i push the gas pedal to the ground. and yes it does have the hydrulic lifters.
