Hi everyone
Here is my situation i bought a 72 240z
That was sitting for many years i dropped and cleaned the fuel tank cleaned out the fuel lines put a new electric fuel pump new filters put 5 gals of 92 octan its now getting clean fuel to the carbs i purchased and installed carb rebuild kit i put new plugs and wires and it is getting spark i fired it up after a oil change and prepped the motor i had to play with the carbs for like a hour to start it had to use quick start to prim it and she ran great for 45 mins or so shut it off now she will not start anymore any ideas or things i should check
P.s the carb next to the firewall sucks in a lot of air the the front not so much?
