83 camaro. 2.8l v6 auto. i picked it up today i breifly looked it over a week ago it ran and drove. Soo 700$ was a decent deal nice body and great interior.

Well when i picked it up today and did the title, It was branded 1983 camaro cpe-z28. decoded the vin and its a z28. why would someone put a v6 in a z28. also hood/a few other misc parts arent originals

well anyway its having carb issues. 2.8l/3 speed/ posi

ok new plugs/cap/rotor/air cleaner/vaccum lines

runs great above 1500 rpm. at idle it move from 500-750 rpm. when you go to take off it hessitates/small puff of black smoke. sometimes when you turn it dies. and most of the time starting it petal has to be to the floor.

Please help i need a starting point??? greatly appreciated

 

Sounds like it is time for a rebuild you should check your electric choke and the choke pull offs also.IMO

 

Black smoke stands out to me as lots of fuel, too much! That means probly a carb issue. Start looking there and read up. I dont know much about carbs or I would help more, sorry.

For any issues if you want to make sure its in good working order(at least the internals and the vaccum lines(which IIRC there are alot of vac. lines on that car) You can do a vac test and a compression test.

Check the vaccum that the car is pulling at idle and see where its at.
Check the compression with a comp tester and see where thats at.

Let us know those numbers and we can rule out bad vaccum leaks, wiped out cam lobes, rings(compression problems). But I severly doubt that engine has any of those issues.


I have to say though take a look deeper into the carb and see what pans out.

 

What about the VIN makes you believe it is a Z28?

 

ok how do i check the choke. it not the original varajet ii. some one swapped it out for the non electronic, but still has electric choke
