I have a evolution .46nt engine. The problem i am haveing is that the engine starts backwards. I know that I am starting the engine the right way. In the past if the engine started backwards I would have to turn it like I was starting it backwards and it would start the correct way. I had the engine put in my closet for about two months to four months. But now the engine starts backwards no matter which way i turn the prop.I an spiningg a 9X6 reverse pitch prop which is smaller that the one that is recominded for the engine

P.S. The engine is on a 24" long airboat (swampbugy if that is what you know it as) but it is a airplane engine. I could not find a pull start conversion for it or an electric start. I also can not use a 12v eletric starter as you can see in the pics below
