Default 25 hp Johnson (stalls) runs out of fuel at idle

Perhaps a float adjustment?
Too slow of idle setting?
rebuilt fuel pump.
The motor runs great at speed.
1989 Johnson.

Loose clamp on a fuel fitting between tank and fuel pump?

you could try to adjust your low speed needle valve. Start with just an 1/8-1/4 of a turn out. This will richen up your idle mixture. Part #14 If that does not do it I would pull the carb and clean it with a new kit installed.

It sounds like ethanol fuel is taking it's toll on this carb and I'm expecting it to re-occur sometime next season.
