I poofed that damn promax again! Had roughly 5 1/2 hours into the break-in. Top left cylinder has pieces on the sparkplug and you can see bits inside. Jay smith has been great to deal with and has been calling checking on progress. Told me I could ramp it up to 6 grand for couple secs and then back down. She has been purring at 3- 4500. 32 to 1, using aces, . Very frustrating. Just crated it up and sentback to him. Was hoping to have it for fastpass rally. Now I'm.scared of the motor! Jim
