I am very happy to report that I my Eagle has been factory repaired. You all were right on about Fox' service. They replaced the piston, ring, mixture needle valve and apparently a brand new sleeve. They installed a new plug, thrust washer and nut and replaced all head screws with brand new one. The charge? $20 for the piston and $5.50 for the mixture needle. That's it!

The repair technician's hand written notes are as follows. Recommendations: 5% to 10% nitro Fox fuel, Fox long plug, 11X6 prop. He reported 13,800 rpm with good transition and idle. He ended with a 'thank you' and signed 'Cuong Nguyen'.

Having just got back from the field today, I will fly the engine next Friday and report back. Thank you all very much.
