Sweetpoison240z

I have a 71 240z with the four screws SUs and just noticed the car having a low idle and fuel puddle in the air filter housing from the front carb. when I turn the fuel mixture knob a the bottom of the carb fuel leaks out with the engine off. Do need to rebuild them? Thank you all ahead if anyone can help.

Osirus we share the same views I bought my car to drive it and have always advocated that with any car. Just in three years me and my Z have been to San Francisco, Grand Junction Colorado, and even Las Vegas a couple times and to local drives from Oxnard,CA to Los Angeles. And wouldnt have it any other way. Parts can get expensive but it would be more expensive if I had someone else working on my car. I do all the work to it and know that car like back of my hand. While delivering I do get a lot of people asking me why the hell im delivering in 240Z and I respond I love driving the thing. Also hearing great stories about how they used to have one or knew someone that had one. A security guard who didnt know what the car was even called it a Mini Corvette. Many people seem to enjoy seeing the car on the road and they always have a smile on their face and a big thumbs up. Specially kids.

Thank you Randy and NewZed for your great input but after hours of researching the web for hours and looking for wiring diagrams for my Z I found out my alternator wasnt getting 12 Volts at the "S" Wire at the T connector. I used a jumper wire from B+ and the "S" and had a great 14.5 at idle with all my accesories turned on. After further diagnostics I found out the previous owner had chopped and completely ruined several important harness connection trying to connect only god knows what. all my lights are brighter now which is good since I deliver pizzas in my Z. Once again thank you. The Z community reallt is a great one.

i ran the wire just like you specified. Still doing the same thing. im thinking of returning it and getting another one I dont want to ruin my battery.

I wanted to know what everyone who did the 240Z to 280ZX IR swap was charging at idle I have the E12-80 electronic ignition with the MSD Blaster 2 coil and electric fuel pump. I also used the plug for the conversion that MSA sells. I checked and my charging voltage is at 15.3V at idle is this normal for this swap?

I recently completed my 240Z alternator to 280zx alternator swap and im completely happy with the way everything got brighter. My only question is what charging voltage is normal for this swap. Ive checked it with my multimeter and see 15.3 volts at idle. Is this normal or should I check for something being wired up wrong. ohh and im used the MSA regulator plug for the conversion designed by one of the members here.
