I have a 75 9.9 johnson that Ihave been trying to get right,first question is that it has a 15 hp carb with a 51 jet which I think is for a 9.9, will that be ok? The next problem is that it will not run with the cover on, but runs ok with it off. Thanks for any info in advance.

exhaust leak from leg into cowl area, it is breathing exhaust, no oxygen, for combustion.
