"2000 Johnson 150 has run good

"2000 Johnson 150 has run good all year. It just started stalling out once you put it in gear and start on the throttle. The only way I can get through it is by hitting the choke. It stalls between 800 -900 RPM,s.Once over a 1000 RPM's it runs flawlessly.When it stalls you can start it right back up and it will idle until you put it in gear and try to take off.
Applied slight pressure to the primer bulb when this happens. No difference. Could it be the carbs?
Is their any type of cleaner or additives recommended? I would like to get through the rest of the fishing season with it prior to rebuilding the carbs.
Thanks in advance for your help."
