No, I don't think it's a "no take off" item at all. Providing you can taxi safely to holding point and stop unless immediately cleared for T/O, you should be fine. I did a solo in a C150 where the ASI was dysfunctional on T/O. I aborted, checked the venturi, a bit of dust, cleared, took off. No problems thereafter. It's the landing that one has to worry about no brakes.
