tube changing

[1930artdeco]

I just need to confirm that I did this correctly. Had a tube that leaked somewhere-not sure where but it did leak. So I popped the outer wall off the rim, pulled the tube and replaced it with another tube. I did not add any cornstarch for lube between the tube and tire. Then I reinflated, seated the tube and popped the sidewall back on the rim. Then fully inflated the tube/tire. Still is holding air. Like I said, I just want to make sure I did this correctly.
