Default 91 AC goes lean on idle

My YS goes lean on idle after a few seconds and quits. If I try at 2000, or even at 2800 it still leans and quits. Top end is 8500 with a 15x8 apc, coolpower 15% and os plug. I have a slimline 4004 muffler, it ran good for about 8 flights, then the problem. Thanks Lee

Have you tried screwing the airbleed in a little?
Part of the problem is the fuel. 20% nitro and 20% oil is what we recommend. That allows a richer setting throughout the low to high range.
