Pre-buy inspection needed in Houston area

[acam37]

I have my RV-8 sold to a fellow from Colorado. He is here to take possession but during the demo ride we experienced a slight roughness on one mag. He is requesting an independent third pary to diagnose the problem and give it the all clear befor taking off on a cross country in an unfamiliar plane. Is there someone around Houston who can look at it in the next day or so? We can fly the plane to your location if needed.
