OMC 2.3 flouid at palne up

[edvardus]

I have a 90 th 2,3 L. Renken 1700, The past season was evreything OK, after winter comes a trouble. At idle runs prefeckt, but when I accelarete to plane at 3000 RPM comes to overfluid the engine and when I not back up the trotle the engine dies, when I accelarate wey slowlly from 2500 to 3000 RPM per mm then I come to a plane and then I can drive to a 4000 RPM. I have changed the distribor cap, cabels, contacs,condensator, the timing and gap is OK, I cleaned the carburetor and the problem is still heare. I dont know what else too due.

Any sugestion

If I understand this correctly, when you give it throttle to accelerate, and you don't back off the throttle, the engine will die,
But if you bring the throttle up slowly, it accelerates fine.
If that is what you mean, then you should check to see if the accelerator pump in the carburator is working correctly. It could also be that the carb is defective and no amount of cleaning or rebuilding will help.

Welcome aboard !

Rebuild the carb. Check the filters also, one in the fitting at the carb.

One in the fuel pump if it has one there.

You might also might want to check the fuel pressure that the fuel pump is giving you. 4-6 psi is what it should give you.

I agree with Don 100%.
Symptom sounds like a classic accelerator pump.
It is usually most noticeable after sitting all winter.

ON the eye I can say that the accelerator pump works, but if correct I dont know, and is not anything to see default, the ball at thre bottom was unablle to get it out,It was stocked in the carbretor, with some dificults I have taked it out. Can thease make a trouble?

How about the fuel filters, are you getting enough fuel to the carb, could be a restriction.

There is also a filter on the fuel pickup tube in the gas tank, that screen clean?

Yes, stuck check balls or damaged, corroded surfaces that they are supposted to seal can cause the problem.

I have too much fuel, it smells when I come fast to 3000 RPM, then I must pull trotle back to 2000 RPM and wait to burn the fuel, and then I go to accelerate very very slowly to come out of water, then I can slowlly accelerate to 4000 RPM and to 30mph when I accelarte more come to the problem like at when I want to pane up. It just too much fuel

The carb needs rebuilding or replacing. Some carbs can't be rebuilt.

It's a 50 / 50 chance even with a pro. rebuiding the carb that it will ever give perfect service to you.

i have resolved this problem I have rebuid the carburetor , but I think the problem was with flapper. The boat goes fine, but I have another problem, when it is hot wont started, I think that is the chocke coil, because when I closed the chocke with hand then it is OK.
