2005 F15 carb

[grinner2]

Hello this is my first post. I bought a good used F15. Does anyone know if there is a check ball inside the carb bowl, underneath the check valve assembly? I am not getting fuel thru the venturi tube. Carb has been cleaned and rebuilt and the diaphragm has been replaced. I removed the bowl and filled it with gas and manually worked the diaphragm assembly. Gas will pump thru the check valve, but if I hold my finger over the hole inside the bowl it will pump a stronger stream of fuel compared to not blocking the hole where I think a check ball might have been. Any help will be appreciated. Thanks

If you post a model #, going to the parts fisch above (in RED, purchase yamaha Parts) will show the break down... That may answer your question...
