Ya, well no. It was an insidious problem of the gas cap seals leaking rain water into the wing tanks... then with the wrinkles in the rubber fuel bladder preventing the water from settling to the low point where the fuel drains are. Of course when you fly, you bank the airplane in turns and the water finds the fuel feed point to the engine. The engine was a Continental IO-520, rated at 285 hp. I loved flying the P206. It was basically a 3/4 ton pickup truck with wings. I found out that you grab a wing tip before preflight and shake the airplane pretty hard. Then wait a bit for the water to find the low point. Ultimately, we discovered the gas cap gaskets were not sealing. Amazing how a simple little thing (wing tank gas cap gasket) can potentially kill ya. BTW, true story about that P206. In the 80's, it was confiscated in a drug bust in South Florida by the PBSO (Palm Beach Sheriff's Office). It went up for auction and a friend of a friend bought it for $15K. (Currently they sell new ones for almost $700K) My friend's father worked for PBSO and gave us a head's up of the auction. The other friend had the cash and was high bidder. Because of the connection, we got to fly 133JK for free except for gas and oil. You just can't beat that deal!
