I’m new to this forum and would appreciate any advice you can offer. I have a ‘72 240Z that is pretty much all original. I’ve owned it for about 2 years (my father-in-law was the original owner). I’ve noticed that if I don’t drive it at least every 1-2 weeks, the gas seems to evaporate from the carburetor. The only way I can start it is to put gas directly into the carburetor and the rubber lines leading to the carbs. This is more than just a hard to start carberated engine...there is no fuel in the carburetor or fuel lines and the fuel pump is not bringing gas to the engine when I’m trying to start it. If I drive it once a week, the Z starts up pretty easily. And the Z runs very smoothly when warmed up with plenty of power. Is this normal? Thanks, Jeff Sent from my iPhone using Tapatalk
