86 evinrude 25, idling in gear the carb seems to load up then motor goes dead. It's a bear to restart, pull plugs they're usually wet. Rebuilt carb, low speed adjustment has little effect.

Start with posting your compression test numbers.------Perhaps inspect replace fuel pump diaphragm , a $10 part.----Is this a tiller motor or remote ?

120 psi, new fuel pump. Tiller. This motor has primer instead of choke. Still put hand over carb to start when cold. Is it possible that I'm getting fuel bleed thru primer when running at idle to flood me out

Compression sounds good.-----Flywheel key checked ?---How did it run for you last season ?----Yes the primer could be defective.----Pinch off the fuel supply to the primer when motor is running.----See if motor smooths out.-----Is the thermostat in place and working properly ?----There are numerous other things to check as well , based on feed back after you test stuff.

did you do a blow test on the carb when finished cleaning it ?
no air should flow in when held upside down
how is the tip on the ls needle ?
float not upside down ?
