Here we are, another new guy on this forum, but I may not really belong here. . . .you tell me!
I own a 95 motorhome on an F53 chassis. 460 mill, of course, weighs just under 20K. The 460 runs smoother than anything I've ever owned. Trouble is, the tailpipes are durn sooty, which tells me it's running rich, no? Or am I lost AND confused? Can this be 'adjusted'?
