I have an old merc 7.5 2-stroke outboard that ran last year. It got semi submerged awhile back and I've just gotten around to cleaning the carb and trying to get it back running. Just a few days ago it would start up with starting fluid but not stay running longer then the fluid lasted. Today I got more into it and couldnt get it to start at all or do anything resembling combustion. At this point, I've put a test light between the spark plugs and the coils and both cylinders apear to be getting spark, I've totally cleaned the carb, and have since even removed the carb and tried spraying fluid directly into the intake to no response still. The compression was good last time I checked. I'm really out of ideas at this point. I had removed the top where the pull line is recently and noticed alot of stuff about timing on the cover as well as some marks someone had put on it I thought perhaps maybe I have thrown off the timing? Any ideas would be greatly appreciated and I'd be glad to answer any questions to further state my case. TIA.
