I have a 1990 Yamaha 115
etxd that seems to be starving for fuel at idle and low rpm.. it will run better if u tap the electric choke constantly until it gets above 2300 rpm and it will run great.. carbs have been cleaned and primer bulb changed

Cleaned by who? What you describe is still a low speed mixture problem usually from dirty jets. I see carbs that was suppose to be clean all the time that was still clogged.

Cleaned and rebuilt kit installed by a Yamaha shop the first time which lasted a short time then I cleaned them which lasted a short time... and I mean by short time like one day on the water and the next is right back to running correct... I checked the filter and pump for trash or a bad diaphragm
