A drop of oil or spit into the valve could had unstuck it . Returning a bike back to usefulness does not mean using electric tape on the handlebars or any other cheap way around ,anyone can do that , to be a mechanic mean to restore the bike back to the way it was new and enjoying doing it .

had a stuck valve, it just wouldn't pump up, my pump or a garage pump.
His pump which he broke trying to pump it up and his riding partner
berating himself for not also having a pump had a torrid few hours.
Returning bikes to usable is not trying to slag off any parsimonious
suggestions, I'd say the fundamental mechanics are more important.
rgds, sreten.
I fail to see what is so dreadful about PVC tape on bars.
