Ed Posted May 27, 2004 Share #2 Posted May 27, 2004 You need to give us some more information. Was the engine rebuilt recently? Did anyone do any kind of work to it? Has it been sitting for a while? Give us some more details. For right now it sound like the timing could be off. And the smoke you see coming out of the intake is vaporized fuel.

beandip Posted May 28, 2004 Share #4 Posted May 28, 2004 2 things , you are talking in code. Please include your location on the profile. I can deal with the english , thats no problem. Have you checked the fuel filters ? Are you running SUs or injection ? Is the car equiped with electric fuel pump and mechanical as well ? The "smoke " coming from the carbs could be from a lean condition caused by the filters being clogged . If when started the float bowls were full of fuel the engine might be able to run for a couple of min. before dieing. Gary:classic: Link to comment Share on other sites More sharing options...
xbangu Posted May 28, 2004 Author Share #5 Posted May 28, 2004 My 1972 240Z car have a 280zx turbo engine in it w/ fuel injection & pump and No, I don't think it have a mech pump. Fuel filter still look good. and it's still doing puff the magic dragon coming out of the intake. I ask some guys and he think it could be timing issue??
