The boat will run now for several minutes and then stall.

It needs help starting with some fuel poured in the carb.

I have found that the carb adjusting screws do not work any longer.

The engine runs smooth with both the screws turned all the way in.

There are NO used carbs on ebay if anyone has one on a garage shelf.

I need a GM250 six cylinder 165 hp single barrel carb.

I will need to change the oil again. There is a slight trace of water
in the engine oil again. The manifold has not stop dripping water yet
from the area under the carb.

I live in Barnegat New Jersey

Thanks
