Can't rely on that compression test...It's good enough to get her to start but I screwed up big time on a friends boat last year thinking it was good. Long story short...not the exact same problem, but I was thinking fuel all the way, then went to reversing gear....finally did a proper compression test and sorted it out...head had to be removed and valves cleaned up...my mistake cost him money (I wasn't charging him but he bought lots of things he didn't need...including a carb and smaller prop)...you may indeed need a carb, however, you need to know that compression.
