monarkman Pro Angler Registered: 05/26/04 Posts: 636 Loc: bryan tx	i have a 1990 or 1991 150hp johnson gt and was wondering what the gapping was on the spark plugs? I was thinking 30 but not sure? _________________________ I bleed Maroon! Gig'em Aggies!

CedarCreekWoody Angler Registered: 06/10/10 Posts: 396 Loc: Cedar Creek Lake & LA	My old mechanic always told me to set them about the thickness of a dine -- two nickels if you don't have a dime! I think I would go with the manufacture's suggestion though... _________________________ Woody Sea-Pro 170 CC 90 HP Saltwater Fishing SE Louisiana and Cedar Creek
