FYI
Many years ago I was ferrying new C-150's from Wichita to Miami to build time, once I got caught in WX and was climbing to get through a sucker hole which promptly closed up on me. Suddenly the engine started sputtering and then died. Needless to say I headed for terra firma, the prop was still turning, throttle was at max and mixture was still where I had it during climb, the engine suddenly came back to life and continued to operate normally thereafter. It did not seem to be bothered by the smell in the cockpit!
