If it's a 5/16 shaft, I'd opt for an adapter for a homelite. I'd say you have a 25cc engine from the stats on that prop. Anything less than 25cc just won't turn that prop as fast, no matter what you do with it. I would be concerned that your plastic prop hub will wear down from vibration and your prop will eventually loosen. The adapter hub for homelite isn't very expensive compared to surgery [X(]
