Gave me a chuckle, Pilot_DAR. I once had the first sign of a stuck valve in my trusty old C150F, also in the circuit at a very remote outback airstrip. A very obliging LAME (with tools) hitched a lift on a fortuitous charter flight, then performed the "indian rope trick" and reamed the valve guide. In a really comforting display of confidence in his work, he then hopped in while I flew him back to his base. All good, and never a repeat performance by the 0-200.
