Hey I just bought a 1974 260z for $1200. Its in amazing condition for the price, no rust, good interior (original), original red paint with little oxidization, and new tires. I couldn't drive it when i bought it due to the fact that it was broken into and the aftermarket MSD ignition was stolen (why the price was low). But i figured if the 4 speed manual transmission was shot or the engine busted i could part it out for a decent profit. Well i bought the MSD ($189 at kragens) hooked it up and turned her on. The sound was amazing but before i could drive it she shut off. It wouldn't idle i could gas it and she would stay running but as soon as I let go of the accelerator it turned off. So my question is why wont it idle? carburetor? (dual webers) Fuel pump? i did replace the fuel filter though it wasn't bad at all. Thanks for your time, Josh
