Not totally shure what ya mean on that one. Gas@carb,spark good.Well are ya shure its gas and not water?
A little more info would be helpfull. What have ya tried to fix it?
Grub
I had to reregister it wouldn't let me use my past info!! I've replace plugs, points , battery new starter had carb rebuilt!! Now gas pools under carb in the intake ! It would suck gas over to the spark plugs
Did check timing & timing belt all marks lined up perfect!!! This boat did set for a year due to me being sick couldn't start boat or use it!!! Could piston rings be stuck?
