"Greetings,
Running at 5000 rpm I have maintained 50mph(on GPS). Yesterday at 5000 rpm I had trouble maintaining 40 mph(on GPS).

I am just out of the 10 hour break in period and have begun using the appropiate fuel mixture for the next 10 hours. Motor sounds great, no new noises. Prop has less than 15 hours on rebuild.

Is this issue carb related? Where should the evaluation process begin?

As always, the tech on this sight are great and a wonderful help.

Brian"
