Default Re: Remove Engine Sprocket Without Puller?

You know what, I was thinking about this and I thought of something.

Why is the chain acting up in the first place? I did some research and I found that 410 and 415 are both 1/2" pitch chain. My plan was to move my old sprocket (from my broken engine) onto the new engine, cause the chain was acting like it didn't fit on the new sprocket. But my question is, why would the chain (415) not fit on the new engine sprocket? Shouldn't all the china kit engine sprockets be the same?

Maybe I got a defective sprocket?
