Fredrick Kerfoot a crit : > > What is piston "Ring Flutter"?? I have an IO360. > Ring flutter is an uncontrolled vibration of the piston rings when pressure against the cylinder wall and rpm are inadequate. > Just how concerned should I be? In my opinion, no need to lose sleep over ring flutter on a Lyc.

I would be concerned...I suggest you check your engine timing...Also if your fuel is old, it has lost some of it's volatility, and I would drain it and replace it with "fresh" gasoline...Are you burning Auto Gas?..The book says that 360 needs 100LL (all of them, 160 and above require it.)....................Good Luck.......................CHEERS!!!!.............................Gene Smith. ----- Original Message ----- From: Fredrick Kerfoot To: engines-list@matronics.com Sent: Wednesday, October 10, 2007 6:37 AM Subject: Engines-List: Ring Flutter?

I guess I just don't see how you relate a question about theoretical ring flutter with engine timing or age of fuel. I'm missing the connection. Actually a 180 only requires 91-96 or 91 mogas with STC. Only the 160 and the 200hp versions need the extra octane.
