mercury 9.8

Hey yall I have a 9.8hp model 110
Problem I'm having is motor is really weak
Checked compression and it's 92psi on both cylinders. I have found the bottom spark plug looks like new like it's not getting spark but it is ..so I'm guessing it's not a hot enough spark our that cylinder is not getting fuel ......eny thoughts on this guy's

92 psi both cylinders is really low. motor should have about 120-130 psi.

there is a single carb that feeds both cylinders.

I was afraid of that ...pulled plug wire off cylinder 2
It starts and idols so I got a dead cylinder ...pull both plugs wires off and removed cylinder 2 spark plug and it's dry as a bone so not getting fuel at all to that cylinder
