Thank you for the feedback. As far as the vent, I was just going through my manuals looking for things that were incorrect with an eye to fix any obvious problems before attempting to replace parts. I will not worry about the vent for now.
We drove it a couple miles to the gas station the other day after tinkering with it and I did not feel the stumble there, so it *could* have been something that got flushed through. I will verify that the issue still exists, then try a separate fuel system.
I didn't notice a fuel pressure spec in the manual. Based on what I have read, is roughly 3psi correct?
As much as anything, I am inclined to rebuild it just because the overalll maintenance on this truck seems to have been sporadic at best and I don't necessarily trust that the carb has the right parts in it. I guess if it is functioning, then there is no real reason to mess with it.
