After liftoff tapping the right brake stops it right away. So I had the shop redo it and the problem went away. I suspect that the A&P was in a bit of a hurry and thought he did not have to rebalance just for a tube, but the took care of it, no charge.
Once before I had a tire changed at a quick and cheap shop, and had vibration and had to go to a better shop to balance it .Problem solved
I am not an A&P, but I have been around both car, cycle, and plane repair shops for 50 years, and was a mechanic in the A F. It seems to me to be good practice, that if you have a problem you look at the last thing that was changed,( ie the tire or tube) and also start with the simplest item first. The mechanics I use for this plane have decades of experience,and lots of satisfied customers. For another plane I use QG Aviation, who built award winners as well as a Osh grand champion, and that it the way they do things.
