Before I headed off on a Uk - Oz lengthy jolly, behind a Gipsy Major Mk 10 -2, Middle Wallop was abuzz with Chippies with like engines. Talking with the engineers there, who also did a final check on mine, I was told there had not been a failure due to the engine itself. Those that did go down were by trainee pilots, carby icing, mag points , fuel probs etc peripheral stuff. A confidence builder !,?. Was for me anyway.
impulse mag points needed regapping in India, a bit of carby icing over the Timor Sea…but that old Gipsy did just keep on noisily humming along.
