After a long hiatus guys, I'm back. Having an issue with my 1993 OMC 5.0L HO Ford engine. Holley Carb'ed, mechanical fuel pump. Haven't been able to run it all year but finally getting to it. This thing is running rich. Really rich. Lot's of black smoke and noxious fumes. I can get it to start and run with the throttle at the half to full settings. Runs pretty rough though. And will not run below half throttle setting. I rebuilt the Holley carb at the end of the year last year but never ran it after that. I have turned the mixture screws in, out, everyway. I'm stuck. Any ideas guys?
As always, thank you in advance for any help you can provide.
