Default Need help with boat carb.

My '83 boat has a Rochester 2 barrel carb on the V-6 engine. I put a new accelerator pump on, but still has a hesitation sometimes. Checking things out I noticed no gas coming from the boosters, even at 3500 rpm. I think all the gas is coming from under the throttle blades.

Boat runs ok on the lake, but seems to not have good initial acceleration for water sking.

Very hard to get at the idle mixture screws, no idea where they are set. Is this where gas would be coming from when the engine is running?

I took off the venturi cluster and there are no emulsion tube inserts in the carb. Is that why there is no gas flowing from the boosters?

Thanks, Tom
