Sixth, show me what engine manuacturer, or aircraft manufacturer recommends the use of "starting fluid" to do an engine start.
I believe it was called Ki Gas priming!
And if you're concerned about fuel in the induction system never ever read the bit about cold weather starting for Gypsy Major engines. It involves holding the tail up so that when you tickle the carb you get a more even level of fuel in the inlet manifold!
