Hello all, after a long summer of rebuilding my 88 merc 100. Its running great except for the idle. Its stalling at idle, sometimes immediately and sometimes will run for a minute or two. I have rebuilt the carbs, fuel pump, thermostat - poppet valve, and water pump - impeller. Compression all +- 5 of 130lbs. Runs smooth while cruising. Any ideas why she stalls?

What's the idle RPM in gear? Probably still carb adjustment. Do a sync and link.
