Hi all
Looking for some advice on a 1990 90hp. Engine fires right up, idles fine and eases into gear.
Lately it started doing something annoying. When trolling along or just a slow cruise it feel like it starts to bog a bit and when I give it throttle or go to WOT it stalls out. Feels like it's getting too much fuel. After It stalls only way to restart it is to do neutral warm up position and choke motor and it fires back up. From then if I slowly go to wot it then runs fine.
I replaced the diaphragm last year but I'm thinking the choke may need adjustment? Or Carb issues adjustments?
Any thoughts would be appreciated.

Start with compression and spark check.
Then check the fuel lines and fuel for water.
Any "new" parts? Any work done lately?
