Got everything on and running great Timing set at 8 degrees with TFI on 85 258. I have the idle mixture set correct. When I hit the gas hard sitting or accellerate hard I get a puff of black smoke. I am running 47 jets. I think they are the right size for me Accelerator pump is on the 2nd hole from the bottom there is no lag or bog when I accelerate so I don't think that is the problem.
Here is what I think the problem is. I am running a 1st stage 9.5 .024 2nd stage 6 power valve. I think it is opening way to early. on the second stage might even be opening to early on the 1st stage. I have to hook a vac guage up and see what it reads when I drive to get the right one. Just wanted to see if you guys concure with me or if you think it is something else.
Thanks
Randal
