Hi all,
I purchased the Evolution 10CC and installed in a Meridian.....Have run about 1 1/2 gallons through it.....runs reliably and can set the high speed needle on the ground to achieve max RPM.....however in the air I cannot get that RPM level....have tried running a little richer and leaner on the ground but no difference in the air. In fact if I lean it up on the ground it really is sluggish in the air. Running 12 x 6 prop......any suggestion ?
