This is my first time here I hope I'm asking in the correct area. My friend has a 1993 mastercraft pro star 190. it has a indman 1993 5.8 liter motor. its running rough and the plug are black. They have had some problem with neighbors and I was going to check the spark plug firing order, tune up then chock etc. Their manual got wet and is not readable. Does any body have the correct firing order. and which plug on the dist is # 1. Also what is the cylinder number lay out? Thanks for any help Max
