Well I used to have the same problem in my 77 ,and in my case it was a dirty gas tank,

Well I'm from the border ,Juarez Mexico ,working on my 12th Datsun z automatic and with working ac ,it hasn't run since 1992 , but I'm making progress ,I hope to find more find more people from my country that is driving more z ,since in Mexico we hardly see one on the road,,,:-D keep the Datsun zetas ,on the road not in the junk yard,,,

My case similar after having my car painted ,new engine I only was able to enjoy it for a few months But family comes before anything and now after 3 years i was able to find his substitute and the one of The best things for only $400 dollars at some point life is always good ,,

looks beautiful,just change the wheels that will make the car look better.also how much did you pay for it......

I just got a one owner 1977z,and i know that is rust on the dog legs but im kind of afraid of start cutting the dog legs,because i have never restore a z before even know that the previous owner was a lawer.he did not know how to work on cars at all the car comes from colorado so i imajine theres rust,but i believe your car is worth saving it ,from what i know the floors,the dog legs are kind of easy to fix as long it dosen't have nothing to do with the frame, also my car has rust like yours near the gas tank door i hope you post some more pictures of your car work ....

Same thing happen to me,but i forgot to replace the oil cap it took about 3 miles,thats when it start to make this weird noise,but mine was still rebuildable even know it was knocking i drive the z back home,but i would say in your case i would get another engine i think its cheaper than rebuild.

I would say find a donor body and tranfer the good parts to the donor,the interior looks not that bad but fixing the firewall and the roof thats another thing...

From my point of view i believe is the throtte body, because my car used to do the same the only thing i did to it,replace the throtte body and then adjust.

Thats what my car used to do,i was told that the thotte switch was bad i checked, and the only thing i had to do was adjust the switch.and afted that the smoke was gone ....

If i am not mistaken that car was on craiglist,beautiful car for the price if thats the same one i was thinking abouth buyin it,but i dont have much experience with carburetors so i found a 1977 280z from the orijinal owner in north park i hope some day i get to see your car i live in east dallas,near down town....
