Default RE: My 2300 only likes one prop

I have read every post on this engine I could find for 3 months before buying one. I had not read anything about changing props causing flameouts. I was surprised that i picked up 1300 rpm by changing 2" in pitch. I would have guessed about half of that.

I did open the engine before running it, and found nothing wrong, including burs in the carb. I have considered all the possibilities that you have mentioned as being the culprit. I just find it very strange that one prop works so well, and a slightly different one is a disaster. Of course the engine was re-tuned for each prop. The low end should not need adjustment because there is no difference in load at low rpm's. The high end will need adjustment with different props, and that's what I did.
