1983 merc 470 170hp carb question

[fmalott]

i have posted before about my 2bbl carb i would always have to prime the carb to start only when sitting for a period of time i rebuilt the carb like every one told me to the best of my knowledge why does this carb still need to be primed when sitting for a bit. i go up to my trailer on the weekends only and i would have to prime to start if i would go out the next morning i would not have to prime only when sitting for a week what am i missing why does this stupid carb still lose it's fuel

The carb would be leaking inside the intake manifold draining the fuel bowl.

If you click on the link below, Alpheus posted several videos in it regarding rebuilding carbs and in one talks about that issue.
