just changed the plugs to brand new ngk g-force gs. car sounds like it runs a little smoother, but it still has a off idle hesitation. EDIT: hesitation was caused by the distributor cap being unaligned haha. looks like the complete cause of my problem is alot of debris coming from my gas tank. looks like im going to need to carry a few extra fuel filters with me when im driving around until all the debris empties from the tank . thanks for the help everyone

it got to the point where it wouldnt start anymore. i changed the fuel filter up front and it starts and idles but now with off idle hesitation. the car seems to run smooth after you get it above a certain rpm. i pulled the plugs today and i will be replacing them. they looks pretty carbon fouled.

i never had the chance to drive it before the fuel pump was removed. electric fuel pump in the rear is completely removed. only filter is the one under the hood before the mechanical pump

sorry guys, i have been busy the past few days and have not had the chance to touch the z. i fixed the leaking heater core so there is no more leak. well, the car cut on me again today when driving down to the post office. it made it there fine, but on the way back, it bogged to half power to where it sounds like its running on 3 cylinders then eventually died 10 house down from my house. i got it started up a few times but it would be running rough for a few seconds before dying again. when i got it home (pushed), it still would not start. i tried spraying the carbs with starter fluid. the car instantly fired up with no bogging for a few seconds then instantly died. i would say the gas tank has 1/4 tank in it. also, my car had the electric fuel pump in the rear removed. my mechanic said the su setup only needs the mechanical fuel pump. also, can that ballast resistor affect my car since im not running points? i might as well replace it if there is a possibility it will.

Thanks for the help everyone, esp stevej i appreciate the help i am getting from you guys. unkle, this is my first carborated project car which i have built. I would like the experience with the help of more knowledgeable z members to possibly find out what happened to my car. Its not only to save money. I used to have a E36 M3 and was always on bimmerforums and helped alot of other members solve their problems as well as me finding out solutions to problems on the m3 i had in the past. I know almost all the fixes and problems the e36 has, and was hoping to one day be as knowledgeable about the 240z as well. *steve, rust in the tank is a possibility, before i put the tank up, it had a lot of rust in it. I clred it and took out i would say 95% of the rust chunks, but there is a possibility there is still some left in there. *walter, i will take a pic of the spark plugs tomorrow *5thhorseman, great suggestion, but i dont think it could be the problem in my case. i live in a very hilly area and was going up and down even steeper hills than the one it bogged on with no problems. *steve, the coil is a month old purchased brand new, possibly faulty? is that the power transistor under the coil? i asked on hybridz and a member there suggested that it could be a faulty power transistor that goes out when it gets hot

hey guys, i was wondering if you could help me possibly point out what happened to my 240z the other night as it would not start back up and i had to get it towed. heres some details on the car: 73 240z 4spd running round top su carbs have not done final tune, running a little rich, fairly new plugs, distributor, wires petronix ignitor electronic ignition current minor issues : plugged in blower control, never tested out slight coolant leak from heater control valve hose (only leaks and makes hissing sounds sometimes) running rich, strong exhaust smell when at stoplight and shoots flames on upshifts tach never worked, just goes straight to 8k rpm when ignition is switched on speedometer recently stopped working water temp sensor does not work I have maybe driven the car a total of 10 times on short trips i would say 20 min tops and the car always ran fine (a little rich as it shoots flames every now and then. however, saturday night 60 degrees out i decided to test it out and drove it for over an hour straight (normal driving not racing) around town never went over 60 mph and the car ran fine. After about an hour of driving, i went to a store and parked it maybe 3 minutes. after i was done, car fired right up and off we went. 2 stop lights later the car starts bogging and showing a loss of 50% power as i was going up a very slight incline. The car then cuts power. I tried restarting it maybe 4 times and it fired up for a good 5 seconds before bogging and cutting again. it wouldnt start again after that so i had to have it towed home. I didnt have time to work on it that night, so i let it sit until today. Today, i checked to see if it has gas in the tank, looks around half tank, also checked to see if any hoses or electrical wires got disconnected and they all look fine. looked where the fuel filter is, and it looks like its flowing fine. Checked under the distributor and it looks okay. after trying to start it 4 times today, it cranked over and is running fine. I just drove it down the street and back today, and its running as if it never had a problem. any ideas would could have caused it to die on the the other night?

hey guys thanks for the helpful replies i appreciate it. turned out the backing plates were bent on the bottom and hitting the drum. Thanks

hey guys, i was wondering if anyone would be able to help me solve my brakes problem. my rears when driving let out a squealing sound from both the left and right drum brakes. the system is bleed correctly and the pedal has a normal solid feel. if i pull the hand brake while driving and hold it on, all the rear dragging sounds go away. the dragging sound i would describe as sounding like a train. i could take pics or a possible video of it making the sounds. thanks
