Hi all, new to site, lots of great info on here but I haven't come across the problem I'm having, so here goes. I've got a 95 roadking, this spring it started running irratically,even just dying a couple times after running good.I replaced fuel valve, wires, plugs.Now it won't start and back fires as I'm trying to start. Plugs have consistantly had black soot build -up, and I haven't been able to see any air/vacuum leaks. Any ideas? Thanks in advance.
