I really hope I don't come off as Mr. Poo Poo here but...........I would be very surprised if the tubes do not pull out of the cowl from engine vibration. I also hope your intention is not to make adjustments with the engine running.
Running???? The only way to adjust a engine if you want it right!
Sorry guys but I will have to dis agree here. Here isn't much room between the spinning prop and wing on a 50cc airplane and that is where you would have to be. The second aspect is that the flight conditions are very different from static. The cowl could have a positive pressure ( or even negative although not as likely ) running temps will be different between flight and static as well as load. The best thing to do is set it up reliably on the ground and then adjust to what you hear during flight. It takes a bit longer but the results are better.
