Re: New to this. I have questions

Probably not the prop but with all the effort you have been to, I’d get a new one and you will want a spare to carry. Ebay can be good for props. As for how many blades are optimal, that’s an unending discussion like fuel mix ratios. The generic answer is that the fewer blades the more efficient because of lower blade tip losses, but there may be lower vibration with a higher blade count. Have you checked the prop shaft for straightness (dial indicator)? I would check the fuel pump for hard diaphragms, and the fuel lines for inside deterioration. Fuel starvation is bad news for t-strokes.
