Posted June 19, 200222 yr comment_9045 Howdy folks, my name is Mac and I just inherited a '73 240z. I need some help to get this car running. Here's the deal:This car ran well and was well taken care of up untill the P.O. parked it (still running fine) about four years ago. It was started and ran poorly about a year ago, then had the fuel tank drained and the (SU) carbs partially disassembled on a hunch by the PO that it might be the carb's fault for the poor running, I'm thinking just bad gas after three years in storage?. What should I do first to get this thing running? Do I need to address the fuel system or just fill the tank? OK, about the carbs: Right now just the floats are off the carbs, otherwise they are assembled. Should I just get a gasket set and put them on the car and see what happens or should I take the carbs off the car and tear them down and start from scratch. I am very mechanically inclined, having built my e30 BMW into a near race car, but don't have any experience with carburation, FWIW.Sorry if I'm not giving you much to work with, I didn't want a super-long post.TIA,Mac "still loyal to the Bimmers" Hooke Link to comment https://www.classiczcars.com/forums/topic/1987-240z-virgin-qs-to-get-car-running/ Share on other sites More sharing options...
June 19, 200222 yr comment_9062 Congrats on your new Z!Check the following for the carbs:1 - Pistons move freely and smooth - and the damper oil is filled2 - Choke mechanism works (it lowers the needle housing/tube at the bottom)3 - Linkage isn't binding or gummed up4 - Open the floats and check the jet to make sure it isn't clogged (or blow thru the inlet)5 - Check the condition of the fuel delivery tube from the float bowl to the carb6 - Check/clean the cylindrical filters in the banjo fittings on the float lidIf these items are fine, I think you can skip the rebuild for now.Make sure you replace any fuel filters.Sounds like bad gas to me.
