I need help I have bought a pontoon boat with a 1979 chrysler out board 115 hp and I can not get it running, It will crank all day long and back fire from time to time but that is it, It is getting fuel,has spark and the compresson check showed 110 on each cylinder. The previous owner put in a set of spark plugs that are champion L 20v. So please help I'm lost.
