I had similar problem before. Sweep profile is not going beyond this point. What is the reason?

Here is a way to get this done:
see attached file
You're on a future version to myself so I can't open your file. But make sure your profile is not constrained by a diameter/radius and that it has a pierce relation with the guide curve.
Your Sketch3 used Convert Entities to get the circle, so the relationship is "on edge" which has the same effect as setting the diameter to be always = 3" (as Bjorn surmised).
To do a Sweep feature, get in the habit of using separate sketches for Path and Profile. So use Sketch2 as your "reference" sketch. (Suppress sketch3) Then create a new Path sketch4 and use convert entities on the horizontal line. Similarly do a new Profile sketch5 and do convert entities on the upper curves. Now do your profile circle (sketch6) on the face of Boss-Extrude1. Make it a small circle off to the side. Now add Coincident mates to sketch4 (origin) and sketch5 (perimeter).
Why not use the Revolve Feature?
Then revolve for the shape like I show then you can use the second feature and that would be the Sweep Feature, all you need to do is make sure you check the merge box when you're making the feature.. What you show is an easy two feature part.. Revolve-Sweep
Path is straight, guide curve has a drop in diameter with radius. Sweeps are constant profiles along a path.
Changing sizes within the profile are more of a loft control.
Looking at how simple this part is revolving it would be a pretty easy way to make it.
*Edit* John beat me while I was typing.
Thanks for the new information.
Separate sketches for path and guide curves are personal preference. I prefer same sketch because, for me, better control of design intent. However, there will most likely be times where you will need to use separate sketches.
You could also refer to your own previous question
Problem is I tried in a previous way but it didn't work. John Stoltzfus and Dan Pihlaja method is working without any problem.
Fair enough, their approach is likely more stable in case of design changes also.
