The reason your Enya is kicking the prop is because it's too lean! This is a standard 4 cycle trait and seems to be more so with the Enya's. How do I know? 2 Enya R120's, 1 .90, 1 .60. I also own the following other 4 strokers, an OS .40, OS .91, Magnum .91, Saito 1.50 and a Saito 2.70 twin. The Saito is another real prop kicker when too lean.
